Compute the current in long straight wire, Physics

Assignment Help:

The magnetic induction at a point 15 cm from a long straight wire carrying a current is 4 X 10 -6 T Compute the current.

(J - 12) B = μoI/2πa I = 2πa X B/μo

Current I                     = 2π X 15 X 10-2 X 4 X 10-6 / 4π X 10 -7 = 3A
