U-shaped magnets, also known as horseshoe magnets, are permanent magnets with a U-shaped cross-section. They are commonly used in a variety of applications, including motors, generators, and loudspeakers. U-shaped magnets can be made from a variety of materials, including iron, steel, and neodymium.
The magnetic field of a U-shaped magnet is strongest at the poles, which are located at the ends of the U. The magnetic field lines flow from the north pole to the south pole, and they are strongest in the region between the poles. The strength of the magnetic field decreases with distance from the poles.
