Question

Which of the following charged particles will experience no magnetic force while in a magnetic field.

A particle moving at a 90 degree angle to the magnetic field.
A particle moving at a 45 degree angle to the magnetic field.
A particle moving at a 180 degree angle to the magnetic field.
A particle motion at a 270 degree angle to the magnetic field.

Answer 1

C. A particle moving at a 180 degree angle to the magnetic field.

Got it correct on test :)

Hope this helps

Answer 2

C. A charged particle only experiences a magnetic force when the cross product of its velocity and the magnetic field is non-zero. This means if the particle is moving parallel or anti-parallel to the field, it experiences zero magnetic force.
