The magnetic force on a charge q moving with velocity v in field B:

qE
qvB sin theta
q²B
qB/v

Show answer and solution

Correct answer: B. qvB sin theta

F = qv × B. Magnitude F = qvB sin theta where theta is angle between v and B. Direction perpendicular to both v and B.

Order the steps of EM wave generation by an accelerating charge

Read exercise and reference answers

Steps

Charge accelerates, creating a changing electric field
Changing E-field induces a changing magnetic field
Changing B-field induces a changing E-field further away
The coupled E and B fields propagate outward as a wave
Wave travels in vacuum at c = 3×10⁸ m/s
