Consider the following statements and select the incorrect statement.
A
The presence of a large magnetic flux through a coil maintains a current in the coil if the circuit continuous.
B
A coil of a metal wire kept stationary in a non uniform magnetic field has an e.m.f induced in it.
C
A charged particle enters a region of uniform magnetic field at an angle of 
to the magnetic lines of force, the path of the particle is a circle.
to the magnetic lines of force, the path of the particle is a circle.
D
There is no change in the energy of a charged particle moving in a magnetic field although a magnetic force is acting on it.
Text Solution
Verified by ExpertsThe correct answer is:
D
When charged particle enters perpendicularly in a magnetic field, it moves in a circular path with a constant speed. Hence its kinetic energy also remains constant.
