## Why do poles attract 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.

### Why do magnets attract opposite?

That pulling force of attraction you feel as magnets stick to each other? It’s the north pole of one magnet drawing the south pole of another magnet toward it. Identical poles will push each other away. So when it comes to magnets, opposites really do attract!

Why do magnets attract each other?

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

What object has opposite poles that attract each other?

Magnets
Magnets can also attract each other, but only if they face in opposite directions. A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other. But the two north poles will push each other away.

## 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.

### 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’s the opposite of attract?

(repel) Opposite of to cause (someone) to have a liking for or interest in something. repel. repulse.

Are two magnets stronger than one?

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.

## How can a magnet attract or repel even if they are not touching?

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.

### What is the most magnetic material in nature?

mineral magnetite
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.

What kind of magnet can be turned on and off?

electromagnet
An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor.

Does a magnet have to touch a magnetic object to attract it?

Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few ‘magnetic’ metals and not all matter. Magnets are attracted to and repel other magnets.

## Do magnetic poles that are alike attract?

The south-seeking pole, or any pole similar to it, is called a south magnetic pole. Unlike poles of different magnets attract each other; like poles repel each other. Bar magnets showing attraction of opposite poles and repulsion of like poles.

### Do two north poles attract?

Based on the basic law of magnetism, like poles repel while unlike poles attract. Therefore, north pole attracts with a south pole, but repels another north pole. Two north poles repel while two south poles also repel.

Do Opposites Attract or repel?

Opposites have been known to attract couples, but opposites can conversely repel couples from one another.

Do like poles attract with permanent magnets?

The determining factor of whether a magnet attracts or repels is the pole. 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. Permanent magnets can also cause a reaction with nonmagnetic items , such as metals and even some liquids.
