Can a permanent magnet be turned off and on?
Electromagnet. it is a piece of metal (usually iron) that is wrapped in copper wire. it is turned on by putting electricity through the copper wire. it then producces a magnetic field when electricity is run through it.
The positively charged subatomic particle that remains when a hydrogen atom loses an electron is called?
A proton
When a gas turns to a liquid the energy of the particles?
When a gas turns into a liquid, the gas cools and then loses energy. This is the process known as condensation.
Why does a magnet loses its magnetism when it is strongly heated or hammered?
A magnet is an alignment of particles in a solid. You can imagine a magnet as a bunch of tiny magnets that are all pointing in the same direction. When they point in the same direction, the little parts add up, and the magnet works like you'd expect. When you heat or hammer a magnet, the little magnetic parts can get jostled and unaligned. When that alignment is disturbed, they no longer point in the same direction and may even cancel other magnetic parts out, weakening and eventualy destroying the magnetism.
When your body loses water it loses electrolytes which is a scientific term for what?
The word electrolytes is a scientific term for salts.
What will happen if water is poured on a magnet?
When we pour water onto a magnet it loses a little bit of magnetic power.
What process of gas loses heat and changes into liquid?
This type of change is called condensation.
What process of gas loses heat and change into a liquid?
This type of change is called condensation.
What would happen if you hit or drop a magnet?
it loses its magnetic properties
What wouold a permanently magnetic substance called?
No magnet is permanently magnetised. If it is dropped from a great height enough times or heated, it loses it's magentism.
Is a hot magnet stronger than a cold magnet?
There's no relationship there. But if you take any permanent magnet and heat it hot enough, it loses some or all of its magnetism.
What are two advantages of a natural magnet over electromagnet?
A natural magnet is permanent - an electromagnet loses its power when it's switched off.
What has happened if a magnet becomes barely magnetic?
There are things (I can't remember their name) that face in one direction on a magnet. When these face in different directions the magnet gradually loses force
How heating demagnetises a magnet.?
A magnet works because the atoms of a magnet are all aligned in only a single uniform direction, in most cases due to the direction of north to south.Heating a magnet causes the alignment to be disturbed and be misaligned, thus losing its magnetic power.The temperature at which a heated magnet loses its magnetism is called the Curie Point named after Pierre Curie husband of Marie Curie.
How does heat affect magnetism?
If one continously heats a particular magnet to high temperatures or long time or both, it loses it magnetism because the particles get excited and start forming no-magnetic arrangements.
What happend to a electromagnet when you turn it off?
It stops behaving like a magnet. It loses all its power.
What happened if magnet dipped in salt?
if a magnet gets dipped is salt it loses some magnetism this can be experimented if you put iron filings in a plastic cup filled with water, you will see the water loses its magnetic field and wont see much movement at all.
