A 2.0-m wire segment carrying a current of 0.60 A oriented parallel to a uniform magnetic field of 0.25 T experiences a force of what magnitude?
A) 0.30 N
B) 6.7 N
C) 0.15 N
D) zero

Question

Quizplus · Accepted Answer

The force on a current-carrying wire in a magnetic field is given by F = I * L * B * sin(θ). Since the wire is parallel to the magnetic field, θ = 0 degrees, and sin(0) = 0, resulting in a force of zero.
