A circular coil 20.0cm in diameter and containing nine loops lies flat on the ground. The Earth's magnetic field at this location has magnitude 8.00

Solutions

Expert Solution

magnitude of magnetic field B = 8 x 10^-5T

diameter of coil = d = 20.0 cm ( 10^-2 m / cm)

= 0.20 m

radius of the coil r = d/2

= 0.10 m

area of the loop A = r²

= ( 3.14 ) ( 0.10 m)²

= 0.0314 m²

The angle between the normal to the coil and the field is 90.0^o - 57.0
