Jan 30, 2014 ... When we say that magnets can become demagnetized, we mean that ... could
drop a magnetized nail several times (as refrigerator magnets ...
Nails and other steel objects can become magnetized when exposed to a
magnet. ... However, exposure to strong magnetic fields cause many of these
atoms to ...
As you heat further, individual spins within domains become more likely to point
opposite to ... Cooling the material will cause magnetic domains to form again at
the Curie .... As also explained in elevated temperatures induce demagnetization.
Apr 7, 2007 ... Permanent magnets can be demagnetized in the following ways: ... A magnet

range ordering disrupted, in much the same way that direct current can cause
ordering. .... just hit it with a hammer very hard or drop it down many times
Magnets cause this maglev train to speed along its track. .... If you stroke an iron
nail with a bar magnet, the nail will become a permanent (or at least ...
Permanent magnets can be demagnetized, however, if they are dropped or

Steel can be magnetized to a certain degree by placing the bar N-S and
hammering it. Ships become magnetised in this way during manufacture, as the
