Can a charged particle be accelerated by a magnetic field? Can its speed be increased?

A magnetic field can be produced by

When a charged particle moves in an elecltric or a magnetic field, its speed is v and acceleration is a

A charged particle moves in a circular path in a uniform magnetic field. If its speed is reduced, then its tiem period will

When a charged particle enters a uniform magnetic field its kinetic energy

Statement-1 Path of a charged particle in a uniform and steady magnetic field cannot be parabolic Statement-2 Magnetic field cannot accelerate a charged particle

The motion of a charged particle can be used to distinguish between a magnetic field and electric field in a certain region by firing the charge

Assertion When a charged particle moves perpendicular to a uniform magnetic field then its momentum remains constant. Reason Magnetic force acts perpendicular to the velocity of the particle.

A charged particle enters a magnetic field at right angles to the field. The field exists for a length equal to 1.5 times the radius of circular path of particle. The particle will be deviated from its path by

The path of a charged particle moving in a uniform steady magnetic field cannot be a

The cyclotron is a device which is used to accelerate charged particles such as protons, deutrons, alpha particles, etc. to very high energy. The principle on which a cyclotron works is based on the fact that an electric field can accelerate a charged particle and a magnetic field can throw it into a circular orbit. A particle of charge +q experiences a force qE in an electric field E and this force is independent of velocity of the particle. The particle is accelerated in the direction of the magnetic field. On the other hand, a magnetic field at right angles to the direction of motion of the particle throws the particle in a circular orbit in which the particle revolves with a frequency that does not depend on its speed. A modest potential difference is used as a sources of electric field. If a charged particle is made to pass through this potential difference a number of times, it will acquire an enormous by large velocity and hence kinetic energy. Which of the following cannot be accelerated in a cyclotron?
