Asked by edward
A circular coil of 30 turns and radius 7 cm is placed with its plane oriented at 90 degrees to a magnetic field of 0.1 T. the fieldis now increased at a steady rate, reaching a value of 0.7 T after 5 seconds. when emf is induced in the coil

V = Area * (Number of turns)*(Rate of change of B-field)
= 30*pi*(.07m)^2*(0.6 T)/5s
= ___ Volts
= 30*pi*(.07m)^2*(0.6 T)/5s
= ___ Volts
