Question

If a charged particle moves in a straight line through some region of space, can you say that the magnetic field in that region is zero?

Answer 1

Answer:

i hope the answer is no

Explanation:

No, we cannot

Two possibilities arise:

The particle could be moving in the direction or opposite to the direction of the magnetic field, so that the force of  qv⃗ ×B⃗   on it is zero

The particle could be moving at an angle to the magnetic field, but still remain undeflected because the net Lorrentz Force on it is zero. This means we have set up an electric field which is opposite to the direction of the cross product of  v⃗   and  B⃗   and having magnitude  vB
