a square coil with 30 turns has sides that are 13 cm long. when it is placed in a 0.26-t magnetic field, a maximum torque of 0.60 n?m is exerted on the coil. What is the current in the coil?
Homework Answers
Here ,
Tmax = 0.60 N.m
B = 0.26 T
N = 30 turns
a = 0.13 m
Now ,
Tmax = NBAI
0.60 = 30*0.26 * I *.13^2
I = 4.55 A
the current in the coil is 4.55 A
