In 1831, michael faraday was the first to realize that an electric current could be induced by passing a magnet through a coil of copper wire. which factor is most essential for the induction of the electric current?

Abeam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. if the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? the value of q = -1.6 × 10-19 coulombs.
