Radius of moving charge in magnetic field..

Force on moving charge in magnetic field ,Ampere circuital law

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 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.

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 _______

Helical motion of charge in magnetic field | Motion of charge in electric and magnetic field

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