According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. True or False.
True, The current induced in a circuit due to a change in a magnetic field is directed to oppose the change in flux and to exert a mechanical force which opposes the motion.
Because like magnetic poles repel each other, Lenz's law states that when the north pole of the bar magnet is approaching the coil, the induced current flows in such a way as to make the side of the coil nearest the pole of the bar magnet itself a north pole to oppose the approaching bar magnet.
