Assertion: Magnetic field can not change the kinetic energy of moving charges.
Reason: Magnetic field can not change velocity vector.

Assertion : Magnetic field do not work on moving charge Reason : Magnetic field do not provide acceleration to charge.

Assertion : Magnetic field do not work on moving charge Reason : Magnetic field do not provide acceleration to charge.

Can a static magnetic field change the momentum of a moving charged particle?

Assertion: The earth's magnetic field does not affect the working of a moving coil galvanometer. Reason: Earth's magnetic field is very weak.

The change in the kinetic energy of a charged particle moving in a uniform magnetic field will be zero when its velocity is

The change in the kinetic energy of a charged particle moving in a uniform magnetic field will be zero when its velocity is

The direction of the magnetic force on a positive charge 'q' moving with velocity 'v' in uniform magnetic field B for the following cases, (i) Magnetic field is out of the plane of paper and velocity vector is eastward. (ii)Magnetic field is directed southward and velocity vector is in south west direction.
