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

  1. AThe sudden increase in the flux passing through the ring causes the ring to move away from the solenoid, in ac
  2. BThe sudden decrease in the flux passing through the ring causes the ring to move towards the solenoid, followi
  3. CThe sudden decrease in the current flowing through the solenoid creates a magnetic field that attracts the met
  4. DThe sudden increase in the current flowing through the solenoid generates a magnetic field that repels the rin

Correct answer

A. The sudden increase in the flux passing through the ring causes the ring to move away from the solenoid, in ac

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.
