WebLenz’s law indicates the direction of the induced current. (The direction of the induced current from Lenz’s law contributes the minus sign in Faraday’s law of induction.) Because like magnetic poles repel each other, Lenz’s … WebElectromagnetic induction A magnet and a coil of wire can be used to produce an electric current. A voltage is produced when a magnet moves into a coil of wire.
WebTo calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: force = magnetic flux density × current × length \ [F = B~I~l\] This is when: F is force... WebElectromagnets Electromagnetism is due to the magnetic fields around electric currents. The fields can cause forces with other nearby magnets which can be used to make motors spin and loudspeakers...
