Question

Current flowing in conductor A is 2A and current
flowing in conductor B is 4A. The ratio of magnetic
field produced around conductor A to the magnetic
field produced around conductor B at a distance 10 cm
from both the conductors is ? ​

Answer 1

Explanation:

the constants get cut when we take the ratio so

magnetic field produced by conductor A = I/r= 2A/(10/100) = 20T

magnetic field produced by conductor B =I/r= 4A/(10/100)= 40 T

the ratio of magnetic field of conductor A to conductor B =20/40 =1/2 = 1:2
