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.
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.
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.
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.
distance between them. The greater the mass of the objects and the closer they are, the stronger the gravitational attraction between them.
YES IT CAN!
Exposure to high temperatures can cause magnets to lose their magnetization and become demagnetized.
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.
it will be demagnetized
When a magnet is exposed to a strong magnetic field from another magnet, the alignment of its magnetic domains can be disrupted, causing it to lose its magnetism and become demagnetized.
Permanent magnets can never be demagnetized because they are made of materials with strong magnetic properties that align in a way that maintains their magnetic field over time.
It is no longer magnetic.
A permanent magnet can be demagnetized effectively by subjecting it to high temperatures or strong magnetic fields in the opposite direction of its magnetization. This disrupts the alignment of its magnetic domains, causing it to lose its magnetism.
Dropping it on a hard surface
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.
A permanent magnet can be demagnetized by subjecting it to high temperatures, strong magnetic fields in the opposite direction, or physical shock. These methods disrupt the alignment of the magnetic domains within the material, causing it to lose its magnetism.
In Australia and the UK, you would spell it "demagnetised". In the US, you would substitute a 'z' - "demagnetized".
