Grip strength drops sharply per each millimeter of distance. Keep in mind that even the smallest gap (e.g., dirt, paint, rust) noticeably weakens the grip. Magnetic products hold most effectively in perfect adhesion; distance nullifies the power. Analyze how rapidly the pull force fall, when the product does not touch tightly to the steel surface. When designing the arrangement, avoid additional spacers.

The following data calculates the estimated force sufficient to cause the slippage of the magnet vertically along a upright steel plate (assuming standard friction coefficient). This value is relative to the distance between the magnet and the metal.

Table 3: Vertical assembly (shearing) - vertical pull
MPL 17x17x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.97 kg / 2.13 pounds 966.0 g / 9.5 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.64 kg / 1.42 pounds 644.0 g / 6.3 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.32 kg / 0.71 pounds 322.0 g / 3.2 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.61 kg / 3.55 pounds 1610.0 g / 15.8 N

When placing a element on a upright plane (e.g., a fridge), it will maintain only approx. 1/5 of its maximum pull force. Gravity as well as a low friction coefficient influence the fact that products slide down easier than they detach. Planning a hanger? Note that the shear force is much weaker than the perpendicular breakaway force. On a smooth steel, the magnet will give way down under a noticeably lighter load. Utilizing a rubberized coating can effectively raise the stability.

A thin sheet is unable to focus the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a weak sheet, the flux will penetrate right through and the holding will be smaller. To utilize 100% of this magnet's potential, you need a suitably thick backing of metal. The material oversaturation causes that on thin elements (e.g., thin profiles), the magnet holds weaker. We suggest choosing the steel thickness from these parameters.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Avoid high temperatures – high temperature can permanently destroy this magnet. With every degree above norm, the magnet's force momentarily decreases. Do not use this magnet in hot environments higher than its safe range. Ignoring the limit will result in permanent loss of magnetic properties.

*Technical advisory: Heat tolerance is determined by both grade, but also on the magnet's shape. Low-profile magnets (low permeance coefficient) may lose charge permanently at lower temperatures than long magnets. Warning indicator in the table signals a risk of irreversible loss for this specific geometry.

Two strong neodymiums interact from a significantly greater distance than a magnet and sheet setup. The connection of two magnets generates a stronger field and a wider radius of action. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a striker plate. Be careful that when attracting two neodymiums, the collision energy is huge. The repulsion force is slightly lower than the attraction, but still impressive.
*The magnetic induction in repulsion mode drops to ~0 Gs at the midpoint between the magnets (caused by magnetic field nullification).
* Calculations apply to shear force of dual same magnets (friction ~0.15 for Ni-Ni layer).

Table 7: Hazards (implants) - precautionary measures
MPL 17x17x3 / N38

Object / Device	Limit (Gauss) / mT	Safe distance
Pacemaker	5 Gs (0.5 mT)	7.0 cm

A strong magnetic field poses a large risk to electronics and pacemakers. These NdFeB products produce a flux that disrupts operation of digital equipment. Remember: the invisible magnetic field acts through matter and housings. Exceptional care must be taken by people with hearing aids and insulin pumps. Also at risk are: mechanical watches, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Table 8: Impact energy (kinetic energy) - collision effects
MPL 17x17x3 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	23.45 km/h (6.52 m/s)	0.14 J
30 mm	38.89 km/h (10.80 m/s)	0.38 J
50 mm	50.19 km/h (13.94 m/s)	0.63 J
100 mm	70.98 km/h (19.72 m/s)	1.26 J

Magnetic elements are delicate – a violent impact against metal risks their cracking. Watch the impact speed – a magnet released freely speeds with massive force. Impact energy can destroy the magnet or dangerous crushing to skin. Hold the magnet firmly during bringing near metal so it doesn't slam with momentum against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when working with large magnets.

Corrosion warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

The magnetic field penetrates through water without any losses. As a result, your magnet will pull a heavier object from the bottom than if you lifted it in the air.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet holds only ~20% of its max power.

2. Steel saturation

*Thin steel (e.g. computer case) severely reduces the holding force.

3. Power loss vs temp

*For N38 material, the critical limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.23

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

Model MPL 17x17x3 / N38 features a low profile and industrial pulling force, making it an ideal solution for building separators and machines. This magnetic block with a force of 31.54 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating strong flat magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. To separate the MPL 17x17x3 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend care, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Using a screwdriver risks destroying the coating and permanently cracking the magnet.

They constitute a key element in the production of wind generators and material handling systems. They work great as invisible mounts under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 17x17x3 / N38, it is best to use two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 17x17x3 / N38 model is magnetized axially (dimension 3 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

This model is characterized by dimensions 17x17x3 mm, which, at a weight of 6.5 g, makes it an element with impressive energy density. It is a magnetic block with dimensions 17x17x3 mm and a self-weight of 6.5 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of rare earth magnets.

Advantages

Besides their tremendous pulling force, neodymium magnets offer the following advantages:

They retain magnetic properties for nearly 10 years – the drop is just ~1% (in theory),
They possess excellent resistance to weakening of magnetic properties when exposed to external magnetic sources,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to present itself better,
Neodymium magnets ensure maximum magnetic induction on a contact point, which allows for strong attraction,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
Possibility of detailed machining as well as adapting to specific applications,
Huge importance in modern industrial fields – they are utilized in hard drives, electric motors, medical devices, as well as modern systems.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Disadvantages

Characteristics of disadvantages of neodymium magnets: tips and applications.

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a strong case, which not only protects them against impacts but also increases their durability
We warn that neodymium magnets can lose their power at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets start to rust. For applications outside, it is recommended to use protective magnets, such as those in rubber or plastics, which secure oxidation and corrosion.
Due to limitations in creating threads and complicated forms in magnets, we recommend using casing - magnetic mount.
Health risk related to microscopic parts of magnets are risky, when accidentally swallowed, which becomes key in the context of child safety. Additionally, small components of these products are able to be problematic in diagnostics medical when they are in the body.
Due to neodymium price, their price exceeds standard values,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Magnet power was defined for optimal configuration, including:

with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
possessing a thickness of min. 10 mm to avoid saturation
with an ground contact surface
under conditions of gap-free contact (surface-to-surface)
under vertical application of breakaway force (90-degree angle)
in stable room temperature

Key elements affecting lifting force

In real-world applications, the actual lifting capacity is determined by a number of factors, listed from most significant:

Distance – existence of foreign body (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity rapidly (even by 50% at 0.5 mm).
Load vector – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Substrate thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the lifting capacity (the magnet "punches through" it).
Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
Surface condition – smooth surfaces guarantee perfect abutment, which improves force. Uneven metal reduce efficiency.
Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Lifting capacity was determined by applying a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet’s surface and the plate lowers the holding force.

Warnings

Do not drill into magnets

Powder created during cutting of magnets is combustible. Do not drill into magnets without proper cooling and knowledge.

Risk of cracking

Neodymium magnets are ceramic materials, which means they are fragile like glass. Collision of two magnets will cause them breaking into shards.

Electronic hazard

Do not bring magnets near a purse, computer, or screen. The magnetism can irreversibly ruin these devices and wipe information from cards.

Pinching danger

Large magnets can break fingers instantly. Never place your hand between two strong magnets.

Avoid contact if allergic

A percentage of the population have a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling may cause a rash. It is best to use protective gloves.

Health Danger

Patients with a pacemaker have to keep an large gap from magnets. The magnetism can interfere with the functioning of the implant.

Swallowing risk

Strictly store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are fatal.

Power loss in heat

Avoid heat. Neodymium magnets are sensitive to heat. If you require operation above 80°C, inquire about special high-temperature series (H, SH, UH).

Respect the power

Use magnets consciously. Their immense force can surprise even experienced users. Be vigilant and do not underestimate their force.

Phone sensors

A powerful magnetic field disrupts the functioning of magnetometers in phones and GPS navigation. Do not bring magnets near a device to prevent breaking the sensors.
