Magnetic field due to currentHard
Question
Two concentric circular coils of 10 turns each are situated in the same plane. Their radii are 20 cm 40 and they carry currents 0.2 A and 0.3A respectively in opposite directions μ0 is the permiability of vaccum then magnetic field inWb/m2 at the common centre is :-
Options
A.
B.
C.
D.
Solution
Bc =
Bnet at centre= B1 ~ B2
B1 =
T = 5μ0B2 =
Bnet at centre = 5μ0 -
