    Current through a coil in a magnetic field

    Question: A coil of 90 turns, of resistance 6 ohm and area 28 cm² moves from a uniform magnetic field of 0.02 Tesla to one of 0.42 Tesla in 3.0 second. What average current flows in the wire (in amp) ? Relevant equations: EMF= (Area * Rate of change of magnetic flux) * Number of turns...
