Magnetic flux density, B, Magnetic flux, Unit of magnetic flux density, Tesla, Unit of magnetic flux, Weber, EMF is induced, When there is a changing magnetic field through a solenoid, Faraday's law of electromagnetic induction, EMF induced is directly proportional to the rate of change of magnetic flux, Lenz's law, Direction of induced current is such that it opposes the change that caused it, North pole brought towards closed ring, Induced current flows anticlockwise, North pole brought away from closed ring, Induced current flows clockwise, North pole brought towards the split ring, No induced current
