Answer 1

Explanation:

horseshoe magnet is a magnet made in the shape of a horseshoe. At the ends of its legs, the magnet has two magnetic poles close together. This shape creates a strong magnetic field between the poles.

Horseshoe magnet with computed magnetic field lines. The two magnetic poles are in close vicinity, which concentrates the field lines and creates a strong magnetic field.

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