French scientist André Marie Ampère found that the magnetism produced by permanent magnets and the magnetism produced by electromagnets are the same kind of magnetism. Because of that, the strength of a permanent magnet can be expressed in the same terms as that of an electromagnet. The strength of magnetism of an electromagnet that is a flat loop of wire throu… WebJul 8, 2024 · The electrical current that flows through the wire interacts with the magnet's magnetic field, resulting in a force that pushes on the wire and causes it to spin around the battery. This force is called the Lorentz … WebThe force between two wires, each of which carries a current, can be understood from the interaction of one of the currents with the magnetic field produced by the other current. For example, the force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions. manuale accreditamento regione abruzzo
