Question

A horizontal power line carries current in the west direction. What is the

direction of the magnetic field due to the current in the power line at a point

above and at a point below the power line? explain.​

Answer 1

Answer:

In the question, current is from east to west and hence the direction of the magentic field would be in the directin of the curl of the fingers. ... Thus, the direction of the magnetic field at a point directly below the horizontal power line is outwards (P′).
