A charged particle is moving along a magnetic field line. What is the magnetic force acting on the particle? (sin 0° = 0, sin π/2 = 1) (a) Opposite to its velocity. (b) Perpendicular to its velocity. (c) Zero. (d) Along its velocity.

Answer: (c). F = qvBsin θ; along a field line θ = 0°. F = qvB × 0 = 0 So the answer is (c) zero.

Moving Charge in a Magnetic Field

A charged particle is moving along a magnetic field line. What is the magnetic force acting on the particle? $\left(\sin 0^\circ = 0, \sin\frac{\pi}{2} = 1\right)$

Show answer and solution

Answer: (c)

$F = qvB\sin\theta$ ; along a field line $\theta = 0^\circ$ .
$F = qvB \times 0 = 0$
So the answer is (c) zero.
