Explain why
A bar magnet is placed upright on a floor (so that the axis of the magnet is vertical). A copper ring is held above the magnet, with it's plane horizontal,and released. The copper ring falls in such a manner that it's axis always coincides with that of the magnet . What will be the acceleration with which the ring will fall? Acceleration due to gravity is 10mper secsquare.
A)g B) [✓]
C)>g. D)the answer depends upon pole

Answer:
The acceleration of the falling magnet will be less than acceleration due to gravity. ... This flow of current will be induced in such a way that it will create a magnetic field which would oppose the change and will result in an upward force acting on the bar magnet and hence decreasing the acceleration of the fall.
