How can iron be demagnetized?
an iron can be demagnetised by ;-hammering it while facing east _west direction -hitting it hard on the ground -connecting it into an ac current while facing the east _west direction .
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?
Magnets are "demagnetized" by extreme heat. If you boil a magnet in water, the heat will demagnetize the magnet.
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
How can a magnet be demagnetized using another magnet?
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.
Why is it that permanent magnets can never be 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.
What happens when something is demagnetized?
It is no longer magnetic.
How can a permanent magnet be demagnetized effectively?
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.
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.
How can a permanent magnet be demagnetized?
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.
Can magnets be temporary?
Electromagnets are temporary magnets made of iron usually that are created by passing a current through a wire wrapped around the iron. There are also ways of making temporary magnets out of ordinary iron objects that can later be demagnetized. I am not wise in the ways of these latter type of temporary magnets.
