Which is the best procedure to make a permanent magnet?

placing a magnetically hard material in a weak magnetic field
placing a magnetically hard material in a strong magnetic field
placing a magnetically soft material in a weak magnetic field
placing a magnetically soft material in a strong magnetic field

Answer;

Placing a magnetically hard material in a strong magnetic field

Explanation;Magnets are those materials that generate magnetic field. Materials may either be magnetic materials or non-magnetic materials. Non magnetic materials are those materials that can not be attracted by a magnet while magnetic materials are those that can be attracted by a magnet.Magnetic materials may be classified as either soft magnetic materials or hard magnetic materials based on the ease of magnetization. Soft magnetic materials are those materials that are easily magnetized and easily demagnetized while hard magnetic materials are hard to magnetize and demagnetized.Hard magnetic materials are used to make permanent magnets. This is done by placing them in a strong magnetic field.
