Answer #1

Current in the wire, I = 3.0 A

Distance of a point from the wire, r = 50 m

Magnitude of the magnetic field at this point is given as:

B

Where,

= Permeability of free space =

= 4* 3.14*10^-7*2*3/ (4*3.14*50)

= 1.2*10^-8T

Hence, the magnitude of the magnetic field at a point 20 cm from the wire is 1.2*10^-8 T.......ANS
