Does a magnet have to be touching an object to repel?
Magnetism can work over a distance, meaning that a magnet does not have to be touching an object to attract it or repel it. Not all metals can be magnets. Only certain metals have magnetic properties, namely iron, nickel, cobalt, and a few rare-earth metals such as neodymium.
What is needed for magnets to repel?
Magnets don't always stick together. If you hold two magnets the wrong way around, they push apart – they repel! In other words, if you hold two magnets together so that like-poles are close together (two norths OR two souths), they repel.
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.
Can magnets repel objects?
Magnets attract many metal items, such as iron filings, but they can also repel each other. What many people seldom notice, however, is that many everyday items are weakly repelled by a magnetic field. The reasons why magnets attract some items and repel others stem from differences in molecular and atomic structure.
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.
Do poles attract or repel?
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. Magnets seem to act something like positive and negative electric charges.
How do magnets attract or 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 happens when magnets 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.
How magnets attract and repel?

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.
Why does magnet repel each other?
Like poles of a magnet 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.
What ends of a magnet repel?
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.
Why do like magnets repel?
Like poles of a magnet 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.
