A long straight wire is bent as shown below. Find the resultant magnetic field B at the centre C of the circular path of radius 2 cm if a current I of 5A is passed through the wire.

Text Solution

Verified by Experts

`B= (mu_(0)I)/(2R)`
`mu_(0)=4 pi xx 10^(-7) ` H
I = 5A
R=2 cm = 0.02 m
`B = (4pi xx10^(-7)xx5)/(2xx0.02) ` Tesla
B = `1.570 xx10^(-4)` Tesla
