Q30. When working near some large air cored inductors you misplace a socket and as you cannot find it you

proceed to energise the system. However, you find that something does not operate as expected. Upon

investigation you find that the socket had fallen into a coil. Select the best explanation for what happened.

The socket became permanently magnetised

The socket changed the inductance of the coil

The socket introduced an air gap into the original core

The socket caused a change in the magnetic circuit shorting out the coil
