A short circuited coil is moved towards a fixed magnet at a constant velocity. When the coil is at a distance x from the magnet it experiences a magnetic force F. Now the number of turns in the coil is doubled and the experiment is repeated with the coil moving with same constant velocity towards the magnet. What will be the magnetic force on the coil when it is at a distance x from the magnet?

A short circuited coil is moved towards a fixed magnet at a constant v

1.	A short circuited coil is moved towards a fixed magnet at a constant velocity. When the coil is at a distance x from the magnet it experiences a magnetic force F. Now the number of turns in the coil is doubled and the experiment is repeated with the coil moving with same constant velocity towards the magnet. What will be the magnetic force on the coil when it is at a distance x from the magnet?
