Magnetic force weakens sharply per each millimeter of gap. Remember that even a microscopic distance (e.g., dirt, paint, dust) noticeably diminishes the holding power. Magnetic products operate strongest during direct contact; distance kills the force. See how quickly the parameters plummet, when the product does not adhere directly to the steel surface. When designing the assembly, discard additional spacers.

The following data shows the estimated weight limit needed to cause the sliding of the magnet vertically on a vertical metal surface (considering typical friction coefficient). The holding force depends on the separation distance between the magnet and the metal.

Table 3: Wall mounting (sliding) - vertical pull
MPL 40x7x3 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	2.14 kg / 4.72 lbs 2142.0 g / 21.0 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	1.43 kg / 3.15 lbs 1428.0 g / 14.0 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.71 kg / 1.57 lbs 714.0 g / 7.0 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	3.57 kg / 7.87 lbs 3570.0 g / 35.0 N

When placing a magnet on a upright wall (e.g., a board), it will maintain only about 20%-30% of nominal attraction strength. Gravity and a weak degree of grip mean that holders slip easier than they pull off. Want to create a hanger? Consider that the shear force is significantly lower than the perpendicular breakaway force. On a slippery surface, the magnet will slip down under a noticeably lighter load. Utilizing a rubberized coating can effectively increase the grip.

A too thin steel cannot focus the entire magnetic field, which squanders power of the magnet. Should you install a neodymium to a weak sheet, the magnetism will penetrate right through and the pull force will drop sharply. To squeeze 100% of this neodymium's potential, you need a suitably thick backing of steel. The saturation effect means that on delicate walls (e.g., appliance housings), the magnet holds weaker. We advise picking the steel cross-section from these parameters.

Classic neodymiums irreversibly lose parameters after exceeding the maximum temperature. Protect against heat – high temperature can permanently demagnetize this magnet. As the temperature rises, the neodymium's force momentarily drops. Do not use this product near heat sources exceeding its safe range. Too high temperature will result in destruction of magnetic properties.

*Engineering note: Temperature resistance depends not only on the material grade, but also on the magnet's shape. Low-profile magnets (low Pc) risk losing magnetic properties under lower heat stress than long magnets. The danger warning in the table signals a risk of irreversible loss for this particular item.

Two magnetic products interact from a wider radius than a magnet and sheet setup. The connection of magnet-to-magnet produces a massive flux and a wider radius of performance. Planning to create a solid fastener? Use a pair of magnets instead of a neodymium and a striker plate. Be careful that when bringing together two magnets, the collision energy is huge. The repulsion force is slightly lower than the connection force, but still impressive.
*The magnetic induction in repulsion mode is approximately ~0 Gs in the exact middle of the gap (due to field cancellation).
* Estimates apply to sliding force of two identical neodymium magnets (friction coefficient ~0.15 for Ni-Ni layer).

A strong magnetic field poses a serious hazard to electronic devices and pacemakers. These magnets produce a field that destroys function of digital equipment. Remember: the unseen radiation penetrates the body and glass. Special caution must be exercised by people with cochlear implants and insulin pumps. Influence will be felt by: mechanical watches, car keys, speakers, and displays. Do not place the magnet near cards, HDD media, or precise measuring instruments.

NdFeB products are prone to chipping – a violent impact against metal causes immediate chipping. Pay attention to connection velocity – a neodymium left loose speeds with massive force. Striking energy can trigger coating fragments or dangerous crushing to skin. Hold the magnet firmly during mounting so it doesn't slam with momentum against the steel surface. A contact at a velocity of dozens of km/h means shattering of the magnet. Use safety goggles when playing with powerful specimens.

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

Water displaces steel, making heavy objects slightly lighter. Note: for permanent underwater work, we recommend magnets with an anti-corrosive (epoxy) coating.

1. Vertical hold

*Note: On a vertical surface, the magnet retains merely ~20% of its perpendicular strength.

2. Plate thickness effect

*Thin metal sheet (e.g. computer case) severely weakens the holding force.

3. Heat tolerance

*For standard magnets, the safety limit is 80°C.

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

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.24

The chart above illustrates the magnetic characteristics of the material within the second quadrant of the hysteresis loop. 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.

Component MPL 40x7x3 / N38 features a flat shape and industrial pulling force, making it a perfect solution for building separators and machines. As a magnetic bar with high power (approx. 7.14 kg), this product is available off-the-shelf from our warehouse in Poland. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

Separating block magnets requires a technique based on sliding (moving one relative to the other), rather than forceful pulling apart. Watch your fingers! Magnets with a force of 7.14 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of wind generators and material handling systems. Thanks to the flat surface and high force (approx. 7.14 kg), they are ideal as hidden locks in furniture making and mounting elements in automation. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

For mounting flat magnets MPL 40x7x3 / N38, we recommend utilizing strong epoxy glues (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. Avoid chemically aggressive glues or hot glue, which can demagnetize neodymium (above 80°C).

Standardly, the MPL 40x7x3 / 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. This is the most popular configuration for block magnets used in separators and holders.

This model is characterized by dimensions 40x7x3 mm, which, at a weight of 6.3 g, makes it an element with high energy density. The key parameter here is the lifting capacity amounting to approximately 7.14 kg (force ~70.02 N), which, with such a compact shape, proves the high power of the material. The product meets the standards for N38 grade magnets.

Strengths and weaknesses of neodymium magnets.

Strengths

Besides their high retention, neodymium magnets are valued for these benefits:

They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
Magnets effectively resist against demagnetization caused by external fields,
Thanks to the shiny finish, the layer of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
The surface of neodymium magnets generates a intense magnetic field – this is one of their assets,
Thanks to resistance to high temperature, they are capable of working (depending on the shape) even at temperatures up to 230°C and higher...
In view of the ability of accurate molding and adaptation to individualized solutions, NdFeB magnets can be created in a wide range of geometric configurations, which increases their versatility,
Versatile presence in future technologies – they find application in data components, electric drive systems, medical equipment, and other advanced devices.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which allows their use in small systems

Disadvantages

Drawbacks and weaknesses of neodymium magnets and ways of using them

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a steel housing, which not only protects them against impacts but also increases their durability
When exposed to high temperature, neodymium magnets experience a drop in force. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complex forms in magnets, we recommend using a housing - magnetic mount.
Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these devices are able to be problematic in diagnostics medical when they are in the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which hinders application in large quantities

Pull force analysis

Maximum lifting capacity of the magnet – what it depends on?

The declared magnet strength refers to the limit force, obtained under optimal environment, namely:

on a plate made of mild steel, effectively closing the magnetic flux
with a cross-section no less than 10 mm
characterized by smoothness
under conditions of gap-free contact (surface-to-surface)
during detachment in a direction vertical to the plane
in temp. approx. 20°C

Impact of factors on magnetic holding capacity in practice

Real force is affected by working environment parameters, including (from priority):

Space between surfaces – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet holds much less (typically approx. 20-30% of maximum force).
Plate thickness – insufficiently thick plate does not accept the full field, causing part of the flux to be escaped into the air.
Material composition – different alloys attracts identically. High carbon content weaken the attraction effect.
Smoothness – ideal contact is possible only on polished steel. Rough texture create air cushions, reducing force.
Temperature – heating the magnet causes a temporary drop of force. Check the maximum operating temperature for a given model.

Lifting capacity was measured using a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a minimal clearance between the magnet and the plate decreases the holding force.

Precautions when working with neodymium magnets

Implant safety

Individuals with a heart stimulator should maintain an safe separation from magnets. The magnetism can disrupt the operation of the life-saving device.

Heat warning

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will destroy its magnetic structure and strength.

Metal Allergy

Some people experience a hypersensitivity to Ni, which is the common plating for neodymium magnets. Frequent touching may cause dermatitis. We recommend wear protective gloves.

Eye protection

NdFeB magnets are sintered ceramics, meaning they are very brittle. Collision of two magnets will cause them cracking into small pieces.

Keep away from children

Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Keep away from children and animals.

Compass and GPS

GPS units and smartphones are highly susceptible to magnetism. Direct contact with a strong magnet can ruin the internal compass in your phone.

Conscious usage

Handle with care. Neodymium magnets attract from a distance and snap with huge force, often faster than you can react.

Combustion hazard

Machining of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Protect data

Very strong magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Bodily injuries

Large magnets can break fingers in a fraction of a second. Under no circumstances put your hand betwixt two strong magnets.
