FAQs about U Shaped Neodymium Magnets
Yes, we support free samples for the sustainable development of our customers.
Normal Bulk orders delivery time is 15-20 days, but if you can provide a forecast plan before placing an order or if we have stock, the delivery date can be advanced.
NdFeB magnets are not as heat-resistant as Alnico magnets, which can withstand temperatures of 450 to 550 °C. NdFeB magnets generally withstand temperatures of around 80 to 220°C.
We can provide zinc coating, nickel coating, chemical nickel, black zinc and black nickel, epoxy, black epoxy, gold coating etc...
The magnetic field of each shape of magnet is different. We can customize the shape and magnetization direction to meet customer requirements.
Professional Knowledge & Buying Guide for Industrial Buyers
Why U Shaped Design? Magnetic Field Behavior Explained?
● The U-shaped structure helps to concentrate the magnetic flux, resulting in a stronger, more focused holding field. This design increases the efficiency of the magnet in clamping applications.
● Suitable for bipolar adsorption scenarios (such as fixtures and jigs)
● Better directionality and stability than traditional bar Magnet
How to Choose the Right Coating for U Shaped Magnets?
● Nickel: General choice, rust and wear resistant, bright silver appearance,Corrosion resistant coating
● Epoxy: Black or gray, suitable for wet/chemical environments
● Zinc: low cost, but not as corrosion resistant as nickel
● Gold / Chrome: Can be used for medical devices or high-end decorative parts
Magnetization Direction: What Industrial Buyers Must Know?
● Axial: points from one arm to the other, suitable for clamping applications
● Diametrical: Less commonly used for U-shaped, but customizable
● Multi-pole: for special sensors/motors
If you can provide drawings or explain the purpose, we can help you determine the most suitable magnetization direction and solution.
Pull Force Calculation for U Shaped Magnets – Don’t Be Misled
U-shaped magnets (also called horseshoe magnets) are widely used in clamping, supporting, lifting and sensing applications due to their unique magnetic field concentrating properties. However, there is a common misconception when it comes to understanding and calculating their pull force. Many users believe that pull force ratings for magnets of different shapes and constructions are universal or directly comparable. This is not the case.
What is Pull Force?
Pull force is the maximum force required to separate a magnet from a steel surface, usually measured in kilograms or pounds. This depends on several factors:
● Magnet material and grade (e.g., NdFeB N52 vs. Alnico 5)
● Condition of contacting surfaces (clean, flat, thick, uncoated steel = best)
● Direction of force (straight-line pull is ideal; sideways shear can significantly reduce holding force)
● Air gaps and coatings (even thin coatings or gaps can degrade performance)
What’s special about U-shaped magnets
U-shaped magnets are designed to direct the magnetic field from both poles to the same surface, effectively concentrating the field into a smaller area. This construction creates a strong local magnetic field, especially at the gap between the poles.
However, this construction adds complexity to accurately measuring pull force:
● The working gap between the poles affects the magnetic field concentration.
● The contact of the magnet to the surface is not always uniform.
● Magnetic field leakage and edge effects lead to nonlinear force distribution.
Common mistakes in estimating pull force
● Assuming that pull force scales linearly with size.
● Larger U-shaped magnets may not produce correspondingly higher pull forces if the inter-pole gap or surface contact is not optimized.
How to Accurately Measure U-Magnet Pull Force
● Use a calibrated pull gauge and test on a flat, thick, mild steel plate.
● Make sure the poles are in full flush contact with the magnet surface.
● Pull perpendicular to the surface to avoid shear effects.
● If the magnet will operate on painted, curved, or dirty surfaces, test under specific conditions.
Customization Guide – How to Communicate Efficiently with Suppliers
● Dimensional drawing or specification (with Dimensional unit)
● Material grade requirements (e.g. N42 / N52)
● Magnetization direction description (e.g. Axial)
● Surface treatment preference
● Packaging method (bulk, foam, blister, etc.)
● Application scenario (to help us recommend the best structure)
