A stress of 210 MPa is applied to a low-carbon steel with an elastic modulus of 211 GPa. After the stress is applied and then re
moved, we note that the permanent strain at 0 stress is 0.1. What was the total strain when the stress was equal to 210 MPa

Answer:
Current in the loop is 0.063 A
Explanation:
Number of turns in the coil N = 150
Radius of the circular loop r = 7.5 cm = 0.075 m
So area
Magnetic field B = 1.5 T
Maximum torque is given
We have to find current in the coil
Torque on circular coil in magnetic field is equal to
I = 0.063 A
