Statement-1: When a magnet falls freely through a closed coil, its acceleration is always less than g. Statement-2: The induced current in the coil opposes the magnet's motion (Lenz's law). Choose the correct option.
- Statement-1 true, Statement-2 true; Statement-2 correctly explains Statement-1
- Statement-1 true, Statement-2 true; Statement-2 does NOT correctly explain Statement-1
- Statement-1 true, Statement-2 false
- Statement-1 false, Statement-2 true
Correct answer: Statement-1 true, Statement-2 true; Statement-2 correctly explains Statement-1
Solution
As the magnet falls through the closed coil, the changing flux induces a current that opposes the magnet's motion (Lenz's law), producing a retarding force. Hence the net downward force is less than mg and the acceleration is less than g. Statement-2 is the correct explanation of Statement-1.
