Question

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

Answer 1

Answer:

1 for p=2A=l 1. l for q=4A=l 2.

d=10cm

As per formula,(mu not)*l

1/(2*pi*d)=B1

(mu not)*l 2/(2*pi*d)=B2

B1/B2=l 1/l 2

Answer:- =1 /2

Explanation:

I hope this answer will help you friends.
