Holders with a hook are indispensable in large-format stores and warehouses for suspending advertisements (POS systems). In workshops and garages, they work perfectly for guiding cables or hanging work lighting.

Yes, the hook is an element screwed into a bushing with a metric thread (e.g., M4, M5, M6 - check description). Check the thread size in the product specification to select matching replacements.

You will get the greatest force by mounting the magnet on a thick, smooth steel surface vertically. When mounting on a wall (vertically), the holding force is much lower due to shear force (the magnet may slide).

The steel housing (cup) shields the magnetic field, directing all its power downwards, onto the contact surface. The housing ensures mechanical durability, which is important in industrial and assembly conditions.

In the bathroom or kitchen, they will work perfectly, provided they are not directly splashed with water. If you are looking for an outdoor hanger, choose a model in rubberized or plastic housing, which is tight.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Strengths

Besides their durability, neodymium magnets are valued for these benefits:

They retain attractive force for around 10 years – the loss is just ~1% (in theory),
Neodymium magnets prove to be exceptionally resistant to magnetic field loss caused by external magnetic fields,
By applying a decorative layer of gold, the element has an proper look,
Neodymium magnets deliver maximum magnetic induction on a their surface, which allows for strong attraction,
Through (appropriate) combination of ingredients, they can achieve high thermal resistance, enabling action at temperatures reaching 230°C and above...
Possibility of detailed modeling and adjusting to concrete applications,
Key role in high-tech industry – they serve a role in data components, drive modules, precision medical tools, as well as other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Problematic aspects of neodymium magnets: tips and applications.

At very strong impacts they can break, therefore we recommend placing them in strong housings. A metal housing provides additional protection against damage and increases the magnet's durability.
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and 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 advise using waterproof magnets e.g. in rubber, plastic
We recommend a housing - magnetic mount, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets are risky, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets 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 increases costs of application in large quantities

Lifting parameters

Maximum lifting force for a neodymium magnet – what contributes to it?

The declared magnet strength represents the maximum value, obtained under ideal test conditions, specifically:

using a plate made of high-permeability steel, serving as a circuit closing element
whose transverse dimension reaches at least 10 mm
with a plane cleaned and smooth
without any insulating layer between the magnet and steel
under axial application of breakaway force (90-degree angle)
at room temperature

Determinants of practical lifting force of a magnet

During everyday use, the real power is determined by many variables, listed from the most important:

Air gap (between the magnet and the metal), because even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet holds significantly lower power (often approx. 20-30% of nominal force).
Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be lost to the other side.
Chemical composition of the base – mild steel attracts best. Alloy steels reduce magnetic permeability and holding force.
Surface condition – smooth surfaces ensure maximum contact, which improves force. Uneven metal weaken the grip.
Thermal environment – temperature increase results in weakening of force. Check the thermal limit for a given model.

Holding force was measured on the plate surface of 20 mm thickness, when a perpendicular force was applied, however under attempts to slide the magnet the load capacity is reduced by as much as fivefold. Moreover, even a small distance between the magnet and the plate reduces the load capacity.

Safe handling of neodymium magnets

Keep away from computers

Data protection: Strong magnets can damage data carriers and sensitive devices (heart implants, medical aids, timepieces).

Caution required

Use magnets with awareness. Their huge power can shock even experienced users. Stay alert and do not underestimate their power.

Pacemakers

Patients with a ICD must maintain an large gap from magnets. The magnetic field can disrupt the functioning of the life-saving device.

Precision electronics

An intense magnetic field interferes with the functioning of compasses in smartphones and navigation systems. Keep magnets close to a device to prevent breaking the sensors.

Permanent damage

Standard neodymium magnets (grade N) lose power when the temperature surpasses 80°C. The loss of strength is permanent.

Shattering risk

Despite metallic appearance, neodymium is brittle and not impact-resistant. Avoid impacts, as the magnet may shatter into sharp, dangerous pieces.

Machining danger

Machining of NdFeB material poses a fire hazard. Magnetic powder oxidizes rapidly with oxygen and is difficult to extinguish.

Pinching danger

Mind your fingers. Two large magnets will snap together immediately with a force of massive weight, crushing anything in their path. Exercise extreme caution!

Product not for children

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

Allergic reactions

Certain individuals have a contact allergy to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. We recommend use safety gloves.
