Question

11
9. Two long parallel conductors carry
currents i1 = 3A and i2 = 3A both are
directed into the plane of paper. The
magnitude of resultant magnetic field at
point 'P' is​

Answer 1

Explanation:

according to ampere's circuital law ,

the magnetic field at P will be ,

Miu0(3+2)

= 5miu0

( if we take downward currents to be positive )
