Two identical magnetic dipoles of magnetic moments 1.0 A-m 2 each, placed at a separation of 2 m with their axes perpendicular to each other. The resultant magnetic field at a point midway between the dipole is:
A
5 × 10 –7 T
B
× 10 –7 T
C
10 –7 T
D
2 × 10 –7 T
Text Solution
Verified by ExpertsThe correct answer is:
B
B 1 = 
= 
= 2 × 10 –7 T
B 2 = 
= 10 –7 T
B net = 
× 10 –7 T
