Question

The magnetic force on a moving charged particle is: i. Perpendicular to the velocity ii. Parallel to the velocity iii. Parallel to the B field iv. Independent of the velocity c. Consider +q moving relative to a B field as shown i. Force is parallel to v ii. Force is parallel to B iii. Force is into the page iv. Force is out of the page d. An electron beam enters a magnetic field region. What path will it follow? i. A ii. B iii. C d. In the magnetic field lab, if the magnetic force F on a wire is a shown below, what is the direction of the magnetic field? Wire (where the current is directed towards the sheet of paper) Which side of the magnet is north pole, which side is south pole? Label on the picture above.

Explanation / Answer

Here,

as magnetic force = q * V X B

hence ,the magnetic force on the particle is perpendicular to both magnetic field and velocity of particle

b) the magnetic force on a moving charged particle is i) perpendicular to velocity.

c)

Now , for the given directions

the direction of force on particle is iv) force is out of the page.

d)

the direction of force on electron is upwards

hence , the correct option is i) A

d)

as F = iL X B

the direction of field is towards left

the right side of magnet is north pole
