COMEDK · Physics · 22. Electromagnetic Induction
A magnet \(N S\) is suspended from a spring and while it oscillates, the magnet moves in and out of the coil \(C\). The coil is connected to a galvanometer \(G\). Then, as the magnet oscillates,
- A \(G\) shows deflection to the left and right with constant amplitude
- B \(G\) shows deflection on one side
- C \(G\) shows no deflection
- D G shows deflection to the left and right but the amplitude steadily decreases
Answer & Solution
Correct Answer
(D) G shows deflection to the left and right but the amplitude steadily decreases
Step-by-step Solution
Detailed explanation
The magnet is attached to the spring. This magnet will execute simple harmonic motion. When a coil is placed in such a way that magnet moves in and out of the coil, an emf is induced in the coil which opposes the movement of magnet in the coil. Due to this induced emf…
