Two parallel wire carry equal current of 10A along same direction and are seperated by distace of 2cm find magnetic field at point which is 2cn away from each wire??
Dear studet B = mo * I / 2 * pi * r = 10^-7 * 2 * 10 / 2 * 10^-2 B = 10^-4 TSo net is [(10–4)2 + (10–4)2 + 2(10–8) Cos 60°]1/2= 10–4[1 + 1 + 2 × ½ ]1/2 = 10-4 × √3 T = 1.732 × 10–4T
Dear studet
B = mo * I / 2 * pi * r = 10^-7 * 2 * 10 / 2 * 10^-2
B = 10^-4 T
So net is [(10–4)2 + (10–4)2 + 2(10–8) Cos 60°]1/2
= 10–4[1 + 1 + 2 × ½ ]1/2 = 10-4 × √3 T = 1.732 × 10–4T
