Magnetic Product Description:

This Neodymium Block Magnet has a Length (L) of 25mm, a Width (W) of 12.5mm, a Height (H) of 3.5mm, and has a 4mm diameter hole. It is an N42 grade magnet and is axillary magnetized. This product is identified by AMF Magnetics product code 22019A.

Uses for our rare earth block magnets:

These Neodymium Block Magnets are popular with signmakers and design companies. Their low profile makes them ideal for applications that require a robust holding capacity as they have a good resistance to sheering forces. Perfect for hanging signs and displays from just about any ferrous metal surface; you can even make use of the thin metal frame supporting office ceiling panels! The large rectangular surface of the polarised faces makes this magnet ideal for applications that require a large area to attach a non-magnetic object to.
