Asked by frank fred

at what velocity must a conductor 75mm long cut a magnetic field of flux density 0.6T if an emf of 9V is to be induced in it? Assuming the conductor, the field and the direction of motion are mutually perpendicular.

Isn't there an equation for this?

E = BLv,
v = E/BL = 9 /0.6•0.075 = 200 m/s
