Question

Find the Magnetic field prouced by a straight current carrying conductor having 5A current throught jt at a distance of 2 metres from it. If the distance of a point and the strength of a current in the wire is doubled what will be the new strength of magnetic field​

Answer 1

Explanation:

I=5A

x=0.2m

magnetic field at a distance 0.2 m away from the wire

B=(4π×10^-7×5)÷2π×0.2

=10×5×10^-7

=5×10^-6 Tesla
