Web(1) Test which ends attract, (2) hold the "old" magnet against the table with one hand so it won't move, (3) hold the "new" magnet in a firm grip in the other hand, (4) make a distance of approx. 1-2 cm. and (5) move the "new" magnet in a D-shape above the "old" magnet. Repeat this motion around 20 times to get results.
WebIt is also possible to demagnetize a magnet by hitting the ends of the magnet with a hammer, which will alter the order of the magnet. To hit a magnet with an object in general, applying force, is a good mechanism to achieve this objective. In the same way you can also use an alternating current field to alter the order of the magnetic poles.
