Magnetic force on a moving charge

What happens when a charged particle moves perpendicular to a magnetic field?

• It continues to move in the same path

• It is deflected due to a magnetic force

• It stops

• It is repelled

What are the factors that affect the magnitude of the magnetic force?

• speed, charge

• magnetic field

• electric field

• both a and b

What happens when a neutral particle passes through a magnetic field?

• It remains moving in the same path

• It is deflected by a magnetic force

• It stops

• It is repelled

F=q x v x B

Which of the following statements is true?

• As q increases, F decreases

• As v decreases. F increases

• F is directly proportional to q, v, and B

• F is indirectly proportional to q, v, and B
