Answer to Question #108745 in Electricity and Magnetism for Befikir

Question

the bar magnet is moved completely through the loop.Determine direction of the current between the two points a and b in the circuit

Answer 1

As per the given question,

When the bar magnet entering into the loop, then due to the motion of the magnet, the flux passing through the loop is getting change. As per the magnetic induction, it will try to oppose the change in the flux in the coil. Hence there will be a opposite polarity of magnetic field will create to oppose the change in magnetic flux.

Hence if north pole reaching to the coil then direction of current will be anti-clock wise.
