Two identical coaxial coils P and Q carrying equal current in the same direction are brought nearer. The current in: |
P increases while in Q decreases Q increases while in P decreases Both P and Q increases Both P and Q decreases |
Both P and Q decreases |
The correct answer is Option (4) → Both P and Q decreases Both coil will experience a magnetic field created by one another. However, due to lenz's law, the current in both coil decreases. |
