Problems#!#Moving charges and magnetism

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

Force on moving charge in magnetic field ,Ampere circuital law

Assertion : Magnetic field interacts with a moving charge and not with a stationary charge. Reason : A moving charge produces a magnetic field.

A: The magnetic field always accelerates a moving charge if the moving charge cuts the field lines. R: When a moving charge cuts the magnetic field lines, the magnetic force on the charge is always non zero.

Explain, how moving charge is a source of magnetic field.

Moving charges in a magnetic field would experience a force.

A charge is moving through a magnetic field. The force acting on the charge is maximum when the angle between the velocity of charge and the magnetic field is _______
