WebA horseshoe magnet is either a permanent magnet or an electromagnet made in the shape of a horseshoe (in other words, in a U-shape). The permanent kind has become the most widely recognized symbol for magnets.: 2 It is usually depicted as red and marked with ′North' and 'South' poles.: 3 Although rendered obsolete in the 1950s by squat, … WebAny current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created. Comment.
