When two like-poles point together, the arrows from the two magnets point in OPPOSITE directions and the field lines cannot join up. So the magnets will push apart (repel). It’s only when you hold unlike-poles together (a north pointing to a south) that magnets stick together (they are attracted).

Why do magnets attract and repel?
Magnets are surrounded by an invisible magnetic field that is made by the movement of electrons, the subatomic particles that circle the nucleus of an atom. The hyperactivity of these electrons gives magnets their ability to attract and repel.
How do magnets attract or repel each other?
Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.
Why does these objects repel to a magnet?
Permanent magnets have electrons spinning in around atoms. This is what causes the repulsion between two north poles, there are spinning electrons which result in circular currents that are in opposite directions in each magnet (the same direction when both north poles are pointing the same way) that repel each other.
What is the most magnetic material in nature?
The most magnetic material in nature is the mineral magnetite, also called lodestone (see Figure below). The magnetic domains of magnetite naturally align with Earth’s axis. The picture on the left shows a chunk of magnetite attracting small bits of iron.
Do magnets work in space?
Magnets can be used in space. Unlike a lot of other items you might bring to space that need additional tools or equipment to function, a magnet will work without any extra help. Magnets don’t need gravity or air. Instead, their power comes from the electromagnetic field they generate all by themselves.
What happens when a part of an electromagnet is disconnected?
If you disconnect the wire, the magnetic field disappears and the nail is no longer a magnet. If you leave the wire connected long enough, the nail’s magnetic domains will realign enough to make it a permanent magnet.
Which ends of magnets attract?
The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another.
Can a magnet ever repel a ferromagnetic material?
Magnets are always attracted to ferromagnetic substances like iron, cobalt, nickel and the alloys containing them (example: steel). Ferromagnetic materials not only get attracted to magnets, but they can also retain the magnetic properties after the magnet is removed.
Where is the strongest force of a magnet present?
All magnets have north and south magnetic poles. The poles are regions where the magnet is strongest. The force that a magnet exerts is called magnetic force.
What would happen if you stroke an iron nail with a magnet?
After stroking the iron nail repeatedly with a magnet, the iron nail will become a magnet. We say that the iron nail has been magnetised. The greater the number of strokes you give the iron nail, the stronger its magnetism. Iron filings are attracted to the magnetized iron nail.
Which is the best procedure to make a permanent magnet?
Take two magnets put one North pole and one South pole on the middle of the iron. Draw them towards its ends, repeating the process several times. Take a steel bar, hold it vertically, and strike the end several times with a hammer, and it will become a permanent magnet.
What is the most magnetic metal on earth?
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.
What are the 4 magnetic materials?
The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals.
