horseshoe magnet. A permanent magnet or electromagnet in which the core is horseshoe-shaped or U-shaped, to bring the two poles near each other.Is a horseshoe magnetic?
A horseshoe magnet is a U-shaped metal object that produces a magnetic field. This magnetic field in invisible, but is responsible for a magnet's notable pull on other metal objects. 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.What is a permanent magnetic field?
Field lines of a permanent magnet go from north to south. Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Inside atoms and crystals you have both electrons and the nucleus of the atom.
