Question

1. The wire shown in the figure carries a current of 10A. What is the magnitude of magnetic field induction at the centre O? Given the radius of the bent coil is 3cm.​

Answer 1

Answer:

Explanation:

Given that,

Current i=10A

Radius r=3cm

Angle θ=360  0  −90  0  =270  

0

 

B=  

4πr

μ  

0

×10×3π  B=  2 π

​  ×10 −4

 

B=1.57×10  

−4

T

Hence, the magnetic field is 1.57×10  

−4

T
