How do magnets attract and repel?
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 do magnets have that attract or repel them to one another?
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. We say the magnets repel each other.
How do magnets 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 causes magnets to attract?
Every magnet has a north pole and a south pole. Placing two unlike poles together causes them to attract. When you try to place two like poles together (north to north or south to south), they will repel each other. The magnets are surrounded by an invisible magnetic field that contains stored-up, or potential, energy.
How can magnets attract or repel each other without 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 does repel mean in magnets?
to push back or away by a force, as one body acting upon another (opposed to attract) The north pole of one magnet will repel the north pole of another.
Can a magnet repel and attract at the same time?
Magnets can either attract or repel each other. A permanent magnet is an object that produces a magnetic field around itself.
Is a compass a magnet?
Essentially a compass is a light weight magnet, generally a magnetized needle, on a free rotating pivot. This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth’s natural magnetic north pole.
Do magnets work 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.
Do magnets work underwater?
One of life’s little questions that people wonder about is this: can magnets work underwater? Water is almost completely non-magnetic, so magnets work underwater the same as they do in air or in a vacuum. Magnets involve force.
Why do magnets always point north?
Answer: Solution: A freely suspended magnet always rests in the north-south direction because the magnetic south pole of the earth lies in the geographic north direction and the magnetic north pole of the earth lies in the geographical south direction.
Why magnet does not have East and West pole?
Since earth is a magnet having magnetic field one of its pole is very close to Geographical north so to facilitate for navigation is better to call as ‘north’ Since magnets having two poles and opposite to each other, obviously other pole shall be named ‘south. ‘ Hence magnet have no east or west pole.
Will water ruin a magnet?
The simple answer is no.
Is magnet safe in water?
No. While magnets are typically coated with nickel, zinc or epoxy to protect them against rust and corrosion from moisture they are not waterproof. Neodymium magnets will work wet or submerged for a short period.
Why do some minerals attract magnets?

Why do magnets attract each other?
One end of a ‘bar’ magnet is a north pole and the opposite end is a South Pole.
What is the strongest part of a magnet?
Question 1 SURVEY 120 seconds Q. What do magnets stick to?
Why do magnetic poles repel?
When the north and south pole ends of a magnetic object are put into close proximity, they form an attraction because the magnetic lines continue together in the same direction. Like poles repel because the lines of force are head-to-head.
