What are the sizes of pocket horseshoe magnets?

The height refers to the distance between the bottom of the magnetic poles and the top of the arch. The height can range from 22.2mm (0.87″) to 75mm (2.95″). 

The taller the pocket horseshoe magnet is, the easier it is for a child to hold whilst they are being taught about magnets and how they work. If the magnet is shorter it means that there is less of a loop (the top of the horseshoe magnet) to grip. 

The width refers the distance between the two widest points of the pocket horseshoe magnet. The width ranges from 22mm (0.87″) to 39mm (1.54″).

The wider the pocket horseshoe magnet is, the more material it can collect due to the increased surface area. If you need to pick up large quantities of ferromagnetic material, then you may require a wide pocket horseshoe magnet.

The depth ranges from 7.9mm (0.3″) to 16mm (0.6″). 

The thicker the pocket horseshoe magnet is, the more material it can collect due to the increased surface area. Therefore if you need to pick up large quantities of ferromagnetic material, then you will require a thick pocket horseshoe magnet. 

The magnetic pull ranges from 1kg (2.2lb) to 4kg (8.8lb).

For educational purposes, the best size of pocket horseshoe magnet to use would be 25 x 22 x 8mm (1 x 0.87 x 0.31″). This is the standard size to suit most general purpose applications,
