Ferromagnetism can be impaired by creating an opposing magnetic field. A wire coil placed around a magnet creates an electromagnetic field. If this is aligned in the opposite direction, it could eventually remove the intrinisic field of the permanent magnet.
In many cases, simply heating a magnet would likewise remove the magnetic field.
Use a degaussing coil (driven by AC, not DC). Gradually reduce the field strength either by reducing the AC current or slowly separating the coil and the object.
There seem to be a couple of issues here. One is the physical destruction of the magnet while the other speaks to the demagnetization of the magnet. Let's take them one at a time.
Magnets can be demagnetized by heating them above their Curie temperature. High temperatures below this can also demagnetize a magnet if the magnet is kept hot for a sufficiently long time. We also know that exposing a magnet to an alternating magnetic field crated by, say, an alternating current, will demagnetize (degauss) them.
The physical destruction of a magnet can be accomplished in many ways. Cut it up, crush it up or whatever. But note that the bits of the magnet will still be little magnets unless something like what was suggested above happens.
Heat it over the flame, drop it many times or just hammer it.
By degaussing. Degaussing is a process of reducing the magnetism of a material by applying an opposite magnetic field.
---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.
Some magnets are metal. Not all magnets are metal (though I can't offhand think of any magnets that don't at least contain metal), and not all metals are magnets.
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
the 4 magnetic materials are iron, steel, copper and nickel
ainting pictures with magnets
magnets can be made destroyed or broken apart
Magnets can be destroyed just like any physical object can be destroyed if enough force is applied. Magnets can also be de-magnetised in a number of ways, including heating them, bending them out of shape, or exposing them to electric current.
They could definitely. Tornadoes do not interact with magnetic fields, but most magnets are very small objects that a tornado would lift up just like it would a pebble. In all the objects carried away when tornadoes have destroyed houses, a few magnets were probably among the debris.

Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.

put magnets and put magnets on a car and put magnets on a car and put the car on the road and put the magnets on the road and put the magnets touch the magnets on the road and on the car
since magnets are all ready magnetised when found in nature called natural magnet artificial magnets that are made by man are called artificial magnets
which is the cheapest magnets
bigger magnets. 'cus bigger magnets have more force(also so called as attraction) . thus, smaller magnets have less attraction.
Some magnets are metal. Not all magnets are metal (though I can't offhand think of any magnets that don't at least contain metal), and not all metals are magnets.
Two household objects that have magnets are: fridge magnets, and sizzlers
