Q State Faraday's laws of electromagnetic induction.
First law
At any time the amount of magnetic flux linked with a closed circuit changes an emf is induced in the circuit. The induced emf lasts thus long as the change in magnetic flux continues.
Second law
The magnitude of emf encouraged in a closed circuit is directly proportional to the rate of change of magnetic flux linked with the circuit.
Q. Point out the direction of the current if any induced to flow in the loop by the changing magnetic field. (Describe is the loop as viewed from above.)s Answer: 1.
Derive a mathematical expression for the period of oscillation of a bar magnet in vibration magnetometer. How do you differentiate Dia, Para and Ferromagnetisms in matter.
