Seven of our eight product lines so far have been built for industrial integration - motors, sensors, filters, signage. This one is different. The horseshoe shape has been the textbook symbol for a magnet for over a century, and there's a reason for that: unlike a disc or a block, a U-shaped magnet shows its two poles side by side where students can actually see them, trace field lines between them, and understand what "north" and "south" mean without having to take anyone's word for it.

Material and Construction
This is a sintered N52 grade NdFeB magnet - the same high-performance rare earth material used across our industrial lines, just formed into the classic horseshoe profile. The core is Nd-Fe-B, finished with a three-layer Ni-Cu-Ni nickel coating for corrosion resistance and a smooth, classroom-safe surface. Dimensional tolerance is held to ±0.05mm, and the standard reference size is F50x50x25mm, though custom sizing is available for different grip strengths or demonstration setups.

Magnetic Performance
Axially magnetized with an approximate pull force of 160KG, this magnet is strong enough to make field effects obvious in a classroom setting without needing specialized lab equipment. Maximum working temperature is rated at 80°C, consistent with standard NdFeB limits - keep it away from heat sources and other strong magnetic fields during storage, same as any sintered neodymium piece.
Where This Gets Used
The education-focused design (noted directly in the product's own classification as "Education" type) targets physics classrooms, school science kits, and DIY magnetism demonstrations where the two-pole visual matters more than raw holding force. It also works for anyone who just wants a magnet shaped the way people expect a magnet to look.

Customization
Available with custom logo printing, custom packaging, and graphic customization - all starting at a minimum order of 100 pieces. For sample orders, lead time runs 15-20 days; for production orders, regular delivery is within 7 days for standard configurations, with larger custom runs quoted individually depending on size and finish.

Handling Notes
Like all sintered NdFeB magnets, this horseshoe shape is brittle under impact - avoid letting pieces snap together at speed, especially given the strong pull force at play. Keep away from electronic devices, credit cards, and anyone with a pacemaker. For classroom use, we recommend brief handling demonstrations rather than free circulation among younger students.
Common Questions
Why choose a horseshoe shape over a disc or block for teaching?
The U shape puts both poles in view at the same time, which makes concepts like field lines and pole interaction much easier to demonstrate than with a shape where the poles are hidden on opposite flat faces.
Can you customize the size?
Yes. F50x50x25mm is our standard reference size, but custom dimensions are available - send us your requirement and we'll confirm feasibility.
What's the minimum order quantity?
100 pieces, which also applies to custom logo, packaging, and graphic options.
What certifications does this product carry?
CE and RoHS compliant, produced under an ISO9001:2000 quality system.
