a metallic wire in a semicircular shape of radius 2.2 cm carries a current of 0.7 A.
Then what is the magnitude of magnetic field at the centre of the semicircle?

Question

a metallic wire in a semicircular shape of radius 2 2 cm carries a
current of 0 7 A
Then what is the magnitude of magnetic field at the centre of the
semicircle?

Vara · Accepted Answer

Magnetic field at the centre of the semicircle:B=μ0I4a    =4π×10-70
74×0 022    =9 99×10-6 T
