Question

statements concerning permanent magnets is false? The north pole of a permanent magnets is attracted to a south pole. All permanent magnets are surrounded by a magnetic field. The direction of a magnetic field is indicated by the north pole of a compass. Magnetic field lines outside a permanent magnet originate from the north pole and end on the south pole When a permanent magnet is cut in half, one piece will be a north pole and one piece will be a south pole. Which one of the following statements concerning the magnetic force on a charged particle in a magnetic field is true? The magnetic force is a maximum if the particle is stationary. The magnetic force is zero if the particle moves perpendicular to the field. The magnetic force is a maximum if the particle moves parallel to the field. The magnetic force acts in the direction of motion for a positively charged particle. The magnetic force depends on the component of the particle's velocity that is perpendicular to the field. Complete the following statement: magnitude of the magnetic force that acts on a charged particle in a magnetic field independent of the sign of the charge. the magnitude of the charge. the magnitude of the magnetic field. the direction of motion of the particle.

Explanation / Answer

here,

2)

the magnetic froce , F = q * v * B * sin(theta)

when theta = 90 degree

the magnetic force is maximum

so, the magnetic force depends on thye component of the particle's velocity that is perpendicular to the feild

the correct option is E)
