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

….. Can be produced by magnetic field.

A stationary charge is surrounded by a magnetic field .

When a charged particle moves in a magnetic field its kinetic energy _______ .

When a charged particle enters perpendicular to uniform magnetic field, path followed by it is ______

(a) Magnetic field lines show the direction (at every point) along which a small magnetised needle aligns at the point). Do the magnetic field lines also represent the lines of force on a moving charged particle at every point? (b) Magnetic field lines can be entirely confined within the core of a toroid, but not within a straight solenoid. Why? (c) If magnetic monopoles existed, how would the Gauss's law of magnetism be modified? (d) Does a bar magnet exert a torque on itsell due to its own field? Does one element of a current-carrying wire exert a force on another element of the same wtre? (e) Magnetic field arises due to charges in motion. Can a system have magnetic moments even though its net charge is zero?

If the speed of a charged particle moving through a magnetic field is increased, then the radius of curvature of its trajectory will _____ .
