Question

The magnitude of magnetic field at a point having perpendicular distance 50mm from a long straight conducting wire carrying a current of 3A is​

Answer 1

Answer:

Magnetic field, B = mu I / 2 pi r

B = 4pi × 10 ^ 7× 3 / 2 pi × 50 × 10^ - 3

|B | = 6 × 10^10 Weber

Answer 2

B Is 0.12 G or 0.12*10^-4
