The vector will be . 5 The flux will be First, flat area perpendicular to 6 For a surface parallel to 7 And for in between If this flux changes an emf will be induced in the area. 8 Consider a copper coil with one loop B A
r For N loops 9 N loops B A r 1 0 FARADAY’S LAW The emf induced in a circuit is directly proportional to the time rate of change of the magnetic flux through the circuit. Or 1 1 If changes with time an emf, , will be produced. Coil in magnetic field. 1 2 Flux through...
