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 respectively. The magnetic induction in weber/m 2 at the center of the coils will be (µ 0 = 4π × 10 –7 Wb/A.m):
Text Solution
Verified by ExpertsThe correct answer is:
C
B P = 
= 
= 4×10 –5 Wb/m 2
B Q = 
= 
= 3 × 10 – 5 Wb/m 2
∴ B = 
= 
= 5 × 10 –5 Wb/m 2
