The north pole of a magnet is brought near an unmagnetised iron bar and the bar is attracted. The magnet is turned round so that its south pole faces the bar. What happens now?
The bar is repelled, because the two poles are now alike
The bar stays still, because the induced magnetism is cancelled
The bar is attracted, because the poles induced in it also reverse
The bar is attracted, because the iron is now a permanent magnet
