Magnetic Effects Of Current Question 184
Question: A current carrying loop is free to turn in a uniform magnetic field. The loop will then come into equilibrium when its plane is inclined at [CBSE PMT 1992; Haryana CEE 1996]
Options:
A) $ 0{}^\circ $ to the direction of the field
B) $ 45{}^\circ $ to the direction of the field
C) $ 90{}^\circ $ to the direction of the field
D) $ 135{}^\circ $ to the direction of the field
Show Answer
Answer:
Correct Answer: C
Solution:
In equilibrium angle between $ \overrightarrow{M} $ and $ \overrightarrow{B} $ is zero. It is happened, when plane of the coil is perpendicular to $ \overrightarrow{B} $
