hey shaleen. i am not getting the concept behind the change in magnetic flux linked with a coil and how does an electron behave like a magnet in presence of a magnetic field.(magnetic domains part)

when electrons move in a circular  path in its orbit, that means current is flowing.we know that , when current flows magnetic field is produced around it. so when we bring a magnet near it, two magnetic fields interact. so either gets attracted or repelled.
 
now for a current carrying coil,  there is a magnetic field associated.
so at point B , magnetic flux is more than at point A. and so on. so if a coil where no current is flowing , moves towards this coil, magnetic field through it increases, and viceversa.
