What is the explanation for the sudden upward movement of a metal ring placed on top of a fixed solenoid, considering the current is switched on?

Options
- AThe sudden increase in the flux passing through the ring causes the ring to move away from the solenoid, in accordance with Lenz's law.
- BThe sudden decrease in the flux passing through the ring causes the ring to move towards the solenoid, following the principles of electromagnetic induction.
- CThe sudden decrease in the current flowing through the solenoid creates a magnetic field that attracts the metal ring upwards.
- DThe sudden increase in the current flowing through the solenoid generates a magnetic field that repels the ring, causing it to move upward.
Correct answer
A. The sudden increase in the flux passing through the ring causes the ring to move away from the solenoid, in accordance with Lenz's law.
Step-by-step solution
Correct Option is : (A)
The sudden increase in the flux passing through the ring causes the ring to move away from the solenoid, in accordance with Lenz's law.
The sudden increase in the flux passing through the ring causes the ring to move away from the solenoid, in accordance with Lenz's law.
