Question
A square coil ACDE with its plane vertical is released from rest in a horizontal uniform magnetic field 
of length 2L. The acceleration of the coil is
of length 2L. The acceleration of the coil is Options
A.less than g for all the time till the loop crosses the magnetic field completely
B.less than g when it enters the field and greater than g when it comes out of the field
C.g all the time
D.less than g when it enters and comes out of the field but equal to g when it is within the field
Solution
When the coil is entering and coming out of the field the magnetic flux in it is changing but when it is within the field the magnetic flux in it is constant.
