Basically, all electrons are naturally little magnets. They produce an electromagnetic field. We won't worry too much about how and why this happens, just take it as given that it does happen. This property of electrons is, for historical reasons, called "spin".
In most materials, the electrons get "paired up": One having a "spin up" will get paired with one having a "spin down", so their magnetic fields cancel out within a single atom or molecule.
However, some materials are ferromagnetic. They have lots of unpaired electrons, so their spins don't cancel out on an atomic level. They may still cancel out with the atom next to them... this is why most iron bars (iron is a ferromagnetic material, and the word "ferromagnetic" actually comes from the Latin word for iron, ferrum) are not magnets: each tiny iron atom has its individual magnetic field pointing in a different direction, so that for every one that's pointing west there's another one pointed east and for every up there's a down and for every south there's a north and so on.
If you can get all the atoms to "line up" with their tiny magnetic fields all pointing the same direction, you get a permanent magnet, like the little toy magnets you can buy.
You can also temporarily make them line up using electricity. An electric current in a coil of wire makes a magnetic field, but if you put a ferromagnetic substance in the center of the coil, it intensifies the field, and you get an electromagnet.
Even if a ferromagnetic material isn't a magnet itself, it's still attracted by other magnets. This is why you can stick a magnet on your (steel) refrigerator, or use one to pick up (iron) nails.
What else can I help you with?
What must you have for an electromagnet to work that you don't need for a regular magnet?
To make an electromagnet work, you need an electric current flowing through a coil of wire, which is not needed for a regular magnet.
How does the magnet work in a fridge magnet?
A fridge magnet works by creating a magnetic field that attracts to the metal surface of a refrigerator. The magnet is typically made of a material, such as iron or a ferromagnetic alloy, that retains its magnetic properties. This allows the magnet to stick to the fridge and hold papers or other lightweight objects in place.
How does a magnet work in space?
In space, a magnet works the same way as it does on Earth. A magnet creates a magnetic field around it that attracts or repels other magnetic materials. This is because the movement of charged particles within the magnet creates a magnetic force. In space, the lack of air or gravity does not affect the magnet's ability to create a magnetic field.
How do fridge magnets work to stick to metal surfaces?
Fridge magnets work by using a magnetic force to stick to metal surfaces. The magnet has two poles, a north pole and a south pole. When the magnet comes into contact with a metal surface, the magnetic field of the magnet interacts with the metal, creating a force that holds the magnet in place. This force is strong enough to keep the magnet attached to the metal surface, allowing it to hold up papers or other lightweight objects.
How can you fix a compass that is next to a magnet?
To fix a compass near a magnet, move the compass away from the magnet to ensure accurate readings. If that doesn't work, try demagnetizing the compass by rubbing a strong magnet in the opposite direction. Finally, calibrate the compass according to manufacturer instructions to reset its accuracy.
Can a Magnet work in any kind of liquid?
I think if you put a magnet in a liquid i think it is not going to work again. I think if you put a magnet in a liquid i think it is not going to work again.
Will a magnet work on Platinum?
No
How do magnetic sweepers work?
They work by using a magnet.
Do magnet bracelets work?
There is no scientific proof whatsoever that magnet bracelets work. There will be a few people who swear by them. And there will always be vendors.
Can you cut a magnet and the magnet still work?
No. You'll end up with two smaller magnets, and each will have less than half the magnetic field strength of the original magnet.
Is this windmill work by magnet?
No its work by wind...hence windmill.
Do magnet motors work?
All motors work on magnets dude!!!! so yes magnet motors do work irrespective if they are AC or DC :D!! hope this is what you were looking for
Can homopolar magnet work with any type of magnet?
Yes that works but first you should design a homopolar magnet because there are no homopolar magnets built, yet !
What does magnet say he want to do when he is an adult?
be a person who work with animals
What causes the magnet to work?
Physics. We can be more specific if you will.
What does magnet say he wants to do when he is an?

Can a LPN work in a magnet hospital?
Answer Two: An LPN can work in a Magnet Certified Hospital. The ANA does not define the role. The hospital may determine who they hire to perform which duties. As long as the LPN is working within their scope of practice and the hospital meets the guidelines required for Magnet Certification an LPN can work at a Magnet Hospital. There is a not a requirement for Magnet status that says you may not employ LPNs. Answer One: No, a LPN cannot work as a Nurse in a Magnet Certified Hospital. The ANA Magnet Organization does not define a roll nor recognize the existence of a LPN. An LPN can work in other capacities such as a Nursing Assistant, Janitor, Unit Secretary, or any other job that they are qualified other than a LPN.
