Question 140

A student is investigating the magnetic properties of two metals, X X\,X and YYY.

  • Metal X X\,X is easily magnetised and quickly loses its magnetisation when the magnetising field is removed.
  • Metal Y Y\,Y is more difficult to magnetise, but it retains its magnetisation for a very long time after the magnetising field is removed.

Which row in the table correctly identifies metals X X\,X and Y Y\,Y and lists their classification as magnetically hard or magnetically soft?
