Question

A straight wire, 0.5 m long, is moved straight up at a speed of 20 m/s through a 0.4-T magnetic field pointed in the horizontal direction. a. What EMF is induced in the wire? b. The wire is part of a circuit of total resistance of 6.0 . What is the current in the circuit

Answer 1

Answer:4.0V

Explanation: EMF FORMULA

E=Blv

according to the question where B is 0.4T and length is 0.5m and velocity is 20m/s

E = 0.4T*0.5*20=4.0V
