Net Force on a Loop in a Non-Uniform Field
A rectangular wire loop with dimensions 8.0 cm × 12.0 cm carries a current of 0.50 A. The loop is situated in a non-uniform magnetic field that is perpendicular to the plane of the loop. The magnetic field has a magnitude of 0.30 T along one 8.0 cm side and 0.20 T along the opposite 8.0 cm side. What is the net force on the loop?
A
4.0 × 10⁻³ N
B
1.6 × 10⁻³ N
C
0 N
D
2.4 × 10⁻³ N
