Question

When a bar magnet is pushed towards from the coil connected to a galvanometer the pointer in the galvanometer deflects identify the phenomenon cause ing this deflection and write the factors on thewhich the amount and direction of the deflection depends state the law describeing the phenomenon.

Answer 1

Electromagnetic Induction is the phenomenon.
#It is directly proportional to the rate of change of magnetic flux.
#Direction of deflection depends on the polarity of the bar magnet brought close to the coil. It always tends to oppose the cause that creates it.Ex: if south polarity is brought close to one side of the coil, that side will develop a north polarity.
The law is Faraday's law of electromagnetic induction.
