Question

2. What are the factors that affect the magnitude of the induced current?

Answer 1

Induces current affect by these factors according to faradays law

1) No. of turns per coil : if on a conductor no. of turns per coil incresaes this increases magnetic flux linked to each coil hence increases the current

2) Increase in strength of magnet : If we increase the no. of magnets then magnetic field increase and with the increase in magnetic field the flux also increases hence the current which is linked by change in flux also increases.

3)Relative motion of magnets: If we are producing current in a coil by relative motion of bar magnets inside the conductor then by increasing the relative speed between magnet and conductor also effects the rate of change of magnetic flux which results in increase in current.
