A charged particle is moved along a magnetic field line. The magnetic force on the particle is

Magnetic field lines

A charged particle moves in a uniform magnetic field. The velocity of the particle at some instant makes an acute angle with the magnetic field. The path of the particle will be

The magnetic field lines______.

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

When a charged particle moves in a magnetic field, does its KE always remain constant?

a. Magnetic field lines show the direction (at every point) along which a small magnetised needle aligns (at the point) Do the magnetic field also represent the lines of force one 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 ' law of magnetism be modified ? d. Does a bar magnet exert a torque on itself due to its own field ? Does one element of a current - carrying wire exert a force on another element of the same wire ? e.Magnetic field arises due to charges in motion . Can a system have magnetic moments eventhough its charge is zero ?

Draw the magnetic field lines for a bar magnet.

A current carrying closed loop in the form of a right angle isosceles triangle ABC is placed in a uniform magnetic field acting along AB. If the magnetic force on the arm BC is F, the force on the arm AC is:

A deutron and an alpha particle move in a magnetic field along the same circular path , then the ratio of their velocities is _________ .

Consider the motion of a chrged particle in a uniform magnetic field directed into the paper. If velocity v of the particle is in the plane of the paper , the charged particle will describe a
