Magnetic field due to currentHard
Question
Two concentric coils each of radius equal to 2π cm are placed at right angles to each other. 3 ampere and 4 ampere are the currents flowing in each coil respectly. The magnetic induction in Weber/m2 at the centre of the coils will be
(μ0 = 4π × 10-7 Wb/A.m.)
(μ0 = 4π × 10-7 Wb/A.m.)
Options
A.10-5
B.12 × 10-5
C.7 × 10-5
D.5 × 10-5
Solution
B1 =
B2 =
B =
⇒ B = 10-7 × 5 × 102
⇒ B = 5 × 10-5 Wb/m2
