Case : Read the passage and answer the question(s).
Consider a coil C1 connected to galvanometer as shown. Another current carrying coil C2 is placed next to the first coil.
In context to this, answer the following question.
What causes the current to flow through the coil C1?
Answer & explanation
Correct answer: option 4
There is current in the coil C2 which when moved w.r.t. C1, causes the EMF to develop and hence, a current to flow. So, chronologically speaking, all are correct.
