B
Magnetic forces do not obey Newton’s third law
C
For very high current, magnetic forces obey Newton’s third law
D
Inside low magnetic field, magnetic forces obey Newton’s third law
Answer
Magnetic forces do not obey Newton’s third law
Explanation
Solution
As the action and reaction are instantaneous in III rd law. But magnetic forces transmit with finite speed c.
