Question

For which of the following conditions will a particle experience no magnetic force? (Assume an external magnetic field is present.)
NOTE: You must provide an explanation for your answer to receive credit.

a.  It is not moving.

b.  It is moving perpendicular to the magnetic field.

c.  It has no charge.

d.  Both (a) and (c) are correct.

e.  All of the above are correct.

2)After reading this fascinating lesson, you and your friend are discussing ways to stop a fast-moving charged particle. He claims this could be done using several very strong bar magnets (in other words, by creating a region with a very strong magnetic field). Clearly explain why you think he is correct or why you think his idea is flawed.
