Question

A proton has a magnetic field due to its spin on its axis. The field is similar to that created by a circular current loop of radius 0.650x10-15 m with a current of 1.05x104 A. Find the maximum torque on a proton in a 2.50 T field:
Options
A 3.84 x 10-26 N.m
B 3.48 x 10-26 N.m
Correct Answer
C 38.4 x 10-36 N.m
D 34.8 x 10-2 N.m
Correct Answer

Option B is the correct answer.

Detailed Explanation

mu=I(pi r2)=1.394x10-26 A.m2. tau=mu B=3.48x10-26 N.m.

Hint

mu=I(pi r2)=1.394x10-26 A.m2.
