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).
Why do north pole and north pole repel each other?
A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away. We say the magnets repel each other . ... The magnet is attracted by the earth’s magnetic north pole and always points in that direction.
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. ... Magnets attract when a north pole is introduced to a south pole.
Why like poles attract each other and unlike poles repel each other?
Hint: When like poles are brought together, all the electrons start spinning in the same direction. And when unlike poles are brought together, all the electrons start spinning in the opposite direction . Thus, like poles repel and unlike poles attract each other.
Why do magnets attract and repel each other True or false?
Answer: This statement is true . In magnetic materials, the electrons in the atoms spin in only one direction. ... Due to this field created by the magnetic force, like poles repel each other whereas the unlike poles attract each other.
Do circles form at the poles?
All the meridians on Earth are great circles. ... All these lines of longitude meet at the poles , cutting the Earth neatly in half. The Equator is another of the Earth’s great circles. If you were to cut into the Earth right on its Equator, you’d have two equal halves: the Northern and Southern Hemispheres.
Can ever there be a magnet without pole?
(a) Yes, there can be a magnet with no pole e.g. in case of a toroid carrying current.
What causes a magnet to repel?
If you hold two magnets the wrong way around, they push apart – 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 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.
Are two magnets stronger than one?
Yes, stacking multiple magnets together can make them stronger. Two or more magnets stacked together will exhibit nearly the same strength as a single magnet of the combined size.
What is the difference between like poles and unlike poles?
A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole. ... Unlike poles of different magnets attract each other; like poles repel each other .
Does rubber attract magnet?
All those materials that are not attracted by a magnet are called non-magnetic materials. They have no net magnetic moment. So when a rubber is taken close to a magnet, we see that it is not attracted by the magnet. Therefore, rubber is a non-magnetic material .
Why do like charges repel?
When a positive charge is brought closer to a negative charge, excess number photons from the positive charge get transferred to the negative charge, so that the number of photons in both the charges are balanced . ... Therefore, like charges repel and unlike charges attract.
Is it true that like poles repel?
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another . This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.
What are like poles answer?
Answer: The two different poles or poles having different charges which attract each other are called like poles. Two same poles or poles having same charges which repel each other are called unlike poles.
Which is a natural magnet?
Magnetite, also known as lodestone , is a naturally occurring rock that is a magnet. This natural magnet was first discovered in a region known as magnesia and was named after the area in which it was discovered.
