Answer 2

Answer:

Steel bar is not at all a magnet.

Surprisingly, it will behave like a magnet once it comes in the influence of electric field. As we know that we can run the iron bar with a magnet to produce temporary magnet. ... If the bar has any iron particles then you can convert it into temporary magnet.
