So we know that magnets are everywhere, but what exactly is a magnet and what is magnetism? A magnet is any object that produces its own magnetic field that interacts with other magnetic fields. Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole.
When most people think of magnetism, they think about the magnetic force experienced between two magnets. The magnetic force is caused by the magnet’s magnetic field and points in the direction of the field lines. If you have two magnets next to each other and their north poles are facing each other or their south poles are facing each other, you can see that the field lines move away from each other, so you feel a repelling force between the two magnets.
How are magnets used?
Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people's bodies.
How do magnets actually work?
The mechanics of how do magnets work really breaks right down to the atomic level. When current flows in a wire a magnetic field is created around the wire. Current is simply a bunch of moving electrons, and moving electrons make a magnetic field. This is how electromagnets are made to work.
How do magnets work simple explanation?
The north pole of one magnet attracts the south pole of a second magnet, while the north pole of one magnet repels the other magnet's north pole. So we have the common saying: like poles repel, unlike poles attract. A magnet creates an invisible area of magnetism all around it called a magnetic field.
What makes a magnet a magnet?
Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. ... In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction. This makes the atoms in these substances strongly magnetic—but they are not yet magnets.
What are 5 facts about magnets?
Facts about Magnets

Some farmers give their cows a magnet to swallow. ...
The ends of a compass needle always point toward earth's north and south magnetic poles. ...
The Earth of one big magnet. ...
Cranes use huge electromagnets to pick up scrap metal in junkyards.
What attracts permanent magnets?
Magnets can either attract or repel each other. A permanent magnet is an object that produces a magnetic field around itself. It is this field that enables them to stick to each other and to some types of metal. Specifically, they stick to ferromagnetic materials like iron and things that contain iron, such as steel.
Can I make a magnet?
A simple temporary magnet can be made with a tiny piece of metal, such as a paperclip, and a refrigerator magnet. Gather these items as well as a smaller piece of metal, such as an earring back or a tiny nail, that you can use to test the magnetic properties of the magnetized paperclip.
