A cylindrical copper wire with radius a = 0.021-m carries a uniform current of 229-A. What is the magnitude of the magnetic field at r = 0.0-m, r = a/2 and r = 2·a?
Homework Answers
magnitude of the magnetic field at r = 0.0-m = 0 T
=> magnitude of the magnetic field at r = a/2 = 2 * 10-7 * 229 * (0.25)/0.0105
= 1.09 * 10-3 T
=> magnitude of the magnetic field at r = 2a = 2 * 10-7 * 229 /0.042
= 1.09 * 10-3 T
