##### Reference no: EM13544384

One hundred turns of insulated copper wire are wrapped around an iron core of cross-sectional area 0.100 m2. The circuit is completed by connecting the coil to a 10-ohms resistor. As the magnetic field along the coil axis changes from 1.00 T to 4.5 Tin 3milliseconds, calculate

(a) The induced emf in the coil

(b) The induced current through the resistor.
