Question

consider a situation in which two lengths of wire are placed close together. If a current ran through one wire, you know what effect would be seen in the second wire. The shape of the wire doesn't alter the effect

Question: An inductor is essentially a long series of circular wires (spiral, actually). If a current began running in the first turn of the coil, what would happen at the other end?

Question 2: Would you say that self-inductance would be a stronger effect at higher or lower frequencies?

Explanation / Answer

1) At the other end an emf will be induced due to the change in magnetic flux when current run at one end. This current will be opposite to the input current. This effect is known as self-induction.

2) self-inductance is a stronger effect at lower frequencies, as it opposes the current by inducing emf which opposes its flow. If input current carries a low frequency the induced current will be stronger to that in order to oppose it.
