- hammering
- heating
- alternating current method
Yes, objects can be demagnetized by exposing them to high temperatures, alternating magnetic fields, or physical shocks. This process disrupts the alignment of the magnetic domains within the material, removing the magnetic field.
Repeated striking, heating, or using AC current will demagnetize a magnet. A small magnetic field may remain.
It can be demagnetised by:
-dropping it many times
-hammering it many times
-heating it over a flame

How can iron be demagnetized?
Iron can be demagnetized by subjecting it to a magnetic field in the opposite direction of its existing magnetization. This can disrupt the alignment of its magnetic domains, causing the material to lose its magnetic properties. Heating iron above its Curie temperature can also demagnetize it by disrupting the alignment of its magnetic moments.
Can a magnet attract to a demagnetized iron rod?
Yes. In this case, the magnet will induce magnetism in the iron, which is originally unmagnetized. Once the magnet is removed, the iron may return to an unmagnetized state; unless the magnetic field near the piece of iron is very strong.
What is the thing that weakens a magnet?
Factors that can weaken a magnet include exposure to high temperatures, physical damage like dropping or hitting the magnet, and exposure to strong magnetic fields in the opposite direction.
A natural force of attraction exerted by the earth upon objects that pulls objects towards earth's center is called?
This force is called gravity. It is responsible for keeping objects on the Earth's surface and causes objects to fall towards the ground when dropped.
The gravitational attraction between two objects is determined by the mass of the two objects and the?
distance between them. The greater the mass of the objects and the closer they are, the stronger the gravitational attraction between them.
Can styrofoam be demagnetized?
YES IT CAN!
Can you name one way that magnets can become demagnetized?
Exposure to high temperatures can cause magnets to lose their magnetization and become demagnetized.
How long does it takto demagnetize an object?
The time it takes to demagnetize an object can vary depending on the size and material of the object. Small objects can be demagnetized in a fraction of a second using an appropriate demagnetizing tool or technique, while larger objects may take longer.
What will happen to the magnet if you put some electricity on it?
it will be demagnetized
What happens when something is demagnetized?
It's no longer magnetic
Which would likely demagnetized a magnetized iron nail?
Dropping it on a hard surface
How can a permanent magnet be demagnetized?
A permanent magnet can be demagnetized by exposing it to a strong external magnetic field in the opposite direction of its original magnetization, heating it above its Curie temperature, or subjecting it to physical impacts that disrupt its magnetic alignment.
Can magnets be temporary?
Yes, magnets can be made to be temporary by using materials that can be easily magnetized and demagnetized, like soft iron. These types of magnets are known as temporary or soft magnets because they lose their magnetism quickly once the external magnetic field is removed.
How do you spell demagnetised?
In Australia and the UK, you would spell it "demagnetised". In the US, you would substitute a 'z' - "demagnetized".
How can a magnet become demagnetized?
A magnet can become demagnetized by exposure to high temperatures, strong magnetic fields, or physical impacts that disrupt the alignment of its magnetic domains. These factors can cause the magnetic domains to lose alignment, weakening or eliminating the magnet's magnetic field.
How can iron be demagnetized?
Iron can be demagnetized by subjecting it to a magnetic field in the opposite direction of its existing magnetization. This can disrupt the alignment of its magnetic domains, causing the material to lose its magnetic properties. Heating iron above its Curie temperature can also demagnetize it by disrupting the alignment of its magnetic moments.
What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
