yes,but it can loose it's property by heating,hammering and dropping

What else can I help you with?

Can the earth be a permanent magnet?

No, the Earth is not a permanent magnet. Earth's magnetic field is generated by the movement of molten iron and nickel in its outer core, creating a magnetic field that fluctuates in both strength and direction over time. It is not a fixed or permanent magnet like a bar magnet.


What type of magnetism is present in a bar magnet?

The known magnetism in a bar magnet is electromagnetism.


Is a bar magnet a temporary magnet or not?

Yes, as long as their spins are aligned, they will attract other materials whose spins are aligned, be they temporary or permanent.


Is the magnet in a compass a permanent magnet or electronic?

A. Compasses typically use a permanent magnet.


What is the difference between the earths magnetic field and a bar magnet?

The Earth's magnetic field is generated by the movement of molten iron in the outer core, while a bar magnet is a permanent magnet made of a material that can be magnetized, such as iron. The Earth's magnetic field is much weaker and more complex than that of a bar magnet, which has a consistent north and south pole.


Is a needle in a compass a permanent magnet?

Yes, it is a permanent magnet.


How are the uses of an electromagnet different from those of a permanent bar magnet?

A bar magnet is made from magnet materials and has a magnetic field at all times. An electromagnetic is not naturally magnet and only has a magnetic field when electricity is passed through it.


Is magnetite a temporary magnet?

No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.


What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?

A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.


Is the magnet in a compass a permanent magnetic or an electromagnet?

PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.


What is another name for a permanent magnet?

Normally permanent magnets are those solid metallic ones we can play with so you can probably get away with calling them an (insert shape here) magnet. e.g. Bar Magnet. As for another name. I don't think it has one. You can't call them electromagnets!


If a magnet bar were heated would it change its magnetic field?

Initially, no. At a certain temperature the bar would suddenly lose its magnetism. This temperature is known as the Curie point of the material. If the magnetism of the bar came from an external source - a solenoid or a permanent magnet - the field would return to its original strength as soon as the bar cooled below the Curie point. If the bar had been itself a permanent magnet almost all the field would stay gone until the bar was re-magnetised by an external field.
