. Find the magnitude of the force between two charges, where the first charge is -2µc and the second charge is 3.5µc separated by distance of 15 cm in air. Also, define the nature of the force.
Answer: The relationship between changing magnetic flux and induced electromotive force is known as Faraday's law of electromagnetic induction: The magnitude of an electromagnetic force induced in a circuit is proportional to the rate of change of the magnetic flux that cuts across the circuit.
