There are materials which turn magnet when passed Electric current through them. I am keen to know whether there are materials that may turn magnetic when HEATED instead of supplying electric current?

I am not aware of any matrial that is not magnetic at, say, room temperature but becomes magnetic if heated. Ferromagnetic materials all act the opposite way from what you're looking for - they lose their magnetsim if heated above the Curie temperature point.
