Consider a 10-cm long piece of a wire which carries a current of 10A . Find the magnitude of the magnetic field due to the piece at a point which makes an equilateral triangle with the ends of the piece.

Explanation

`B =(mu_oi)/(4pid) (sin theta_1 + sin theta2)`
`. `= (10^(-7)xx10)/(sqrt75xx10^(-2) ((1)/sqrt2+ (1)/sqrt2 ))`
`. `=11.54xx10^(-6) T `
`=11.54muT` .
