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.
Magnets can lose their magnetic properties if exposed to high temperatures, leading to a loss of alignment of the magnetic domains within the material. Additionally, subjecting a magnet to strong external magnetic fields can also demagnetize it by rearranging the magnetic domains. Cutting or scratching a magnet can also disrupt its internal structure and result in a loss of magnetism.
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.

How many types of magnets are there?
none
What are the types of magnets?
There are permanent magnets, which retain their magnetism once magnetized, and temporary magnets, which only exhibit magnetic properties when exposed to a magnetic field. Permanent magnets can be further classified into ferromagnetic, ferrimagnetic, and rare-earth magnets based on their composition and magnetic properties.
Are magnets metal?
No, magnets are not metal. Magnets are objects that produce a magnetic field, which can attract or repel certain types of metals, but they are typically made from materials like iron, nickel, or cobalt.
Do magnets attract all metals?
No. Magnets do not attract gold, silver, aluminum, brass, copper or lead. Magnets will attract nickel and iron or steel.
Do magnets attract or repel in vacuum?
Magnets attract or repel in a vacuum just as they do in regular air. The absence of air or other material does not affect the magnetic force between magnets.
How can magnets change?
magnets can be made destroyed or broken apart
Can magnets wear out?
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.
Do tornadoes pick up magnets?
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.
What are some names of small magnets?
Some names of small magnets include neodymium magnets, rare earth magnets, ceramic magnets, and ferrite magnets.
How can be destroyed?
---- 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.
How do you make a flying car with 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
What are magnets and artificial magnets?
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 are the cheapest magnets?
which is the cheapest magnets
How many types of magnets are there?
none
Which are better Little magnets or bigger magnets?
bigger magnets. 'cus bigger magnets have more force(also so called as attraction) . thus, smaller magnets have less attraction.
What household objects have magnets in?
Two household objects that have magnets are: fridge magnets, and sizzlers
Do some kitchen toys have magnets?
Some of them do have magnets. Childrens alphabet magnets are an example.
