Why do magnets with the same pole repel each other?
This is because when the two magnets of like poles are kept facing each other the lines of forces are in opposite directions.
So the like poles repel each other.
When the unlike poles of a bar magnet face each other the magnetic lines of force are in the same direction and hence unlike poles attract each other..
What happens when two magnets repel each other?
In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel. … 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).
What is it called when magnets repel each other?
A magnet is a very special metal. … Also, if the two poles are the same, the two magnets will push away, or repel, from each other. This is called magnetism.
Do magnets get weak?
Do magnets get weaker? … Several factors can weaken the magnetism in a magnet. If a magnet is stored close to heat, strong electrical currents, other magnets, or radiation, it can lose its strength. Additionally, high humidity can corrode neodymium magnets.
Which bar is magnetic?
Alnico and Neodymium Bar Magnet The primary components of Alnico magnets are aluminium, nickel, cobalt, and iron.
What is the simplest requirement for an electromagnet?
A wire that has electrical current running through it creates a magnetic field. In fact, the simplest electromagnet is a single wire that is coiled up and has an electric current running through it. The magnetic field generated by the coil of wire is like a regular bar magnet.
What are the two poles that magnets have?
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.
How do magnets repel and attract?
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. … Magnets attract when a north pole is introduced to a south pole. If like poles are introduced, either north to north or south to south, the magnets repel.
What material is most effective at reducing attraction between two magnets?
bismuthYou can insert two pieces of bismuth against each magnet. Bismuth repels (partly) magnetic fields and so the space between will have less magnetic field strength.
Are 2 magnets stronger than 1?
Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.
What metals do magnets attract?
Ferromagnetic metals are strongly attracted by a magnetic force. The common ferromagnetic metals include iron, nickel, cobalt, gadolinium, dysprosium and alloys such as steel that also contain specific ferromagnetic metals such as iron or nickel. Ferromagnetic metals are commonly used to make permanent magnets.
