A horseshoe magnet is a magnet made in the shape of a horseshoe. The magnet has two magnetic poles close together. This shape creates a strong magnetic field between the poles.

It is one type of permanent magnet, meaning that it stays magnetized, as opposed to an electromagnet, whose magnetic field can be started and stopped.[1]

Magnetic field of a horseshoe magnet. The field is greatest where the lines are densest, around the poles (lower) Long U-shaped horseshoe magnets, on a high-power magneto used to power a lighthouse.

The purpose of a horseshoe magnet's shape is to place the poles as close as possible together.[2] The total magnetic flux is the same,[i] but the field is greater, as it is spread over a smaller volume. A horseshoe is used, rather than a simpler C-shaped magnet, which is also used, because this places the maximum amount of magnetised material into the magnet, for given dimensions around the poles. A particularly large horseshoe magnet is U-shaped with long parallel sides, rather than the classical horseshoe.

Electromagnets are also constructed as horseshoes. These may have either one or two coils wound on them. As most coils are wound by machine, the coil formers are straight. They are thus usually placed as two coils, one on each side of a U-shaped horseshoe.

A horseshoe magnet can be created by bending a bar magnet into a horseshoe shape.[2][3]
