How do magnets work BBC Bitesize?
If you bring two bar magnets together, there are two things that can happen, attraction and repulsion : if you bring a north pole and a south pole together, they attract and the magnets stick together. if you bring two north poles together, or two south poles together, they repel and the magnets push each other away.
What are magnets made of BBC Bitesize?
Magnets are made from magnetic metals – iron, nickel and cobalt. These are the only pure metals that can be turned into a permanent magnet. Steel is an alloy of iron and so can also be made into a magnet.
What is a magnetic force BBC Bitesize?
A magnet creates a magnetic field around it. You cannot see a magnetic field, but you can observe its effects. A force is exerted on a magnetic material brought into a magnetic field. The force is a non-contact force because the magnet and the material do not have to touch each other.
How are magnets used in everyday life KS2?
Common uses of magnets include the compass, vending machines, refrigerator magnets and electric motors. Some types of trains even levitate above magnetized rails! Without magnets, the world would be a very different place.
How do magnets attract and repel ks2?
If you put two north poles or two south poles together, they will repel. If you put two opposite poles together, they will attract.
What are magnets KS2?
A magnet is made from magnetic materials such as iron, nickel, steel, or cobalt. Magnets have two poles, north and south. Magnets have an invisible magnetic field that allows them to attract or repel certain materials. Your children will learn about magnets in science at KS1 and KS2.
What are the properties of a magnet for kids?
The three properties that all magnets have are that they all attract (or stick to) certain metals, they have north and south poles (ends), and two of the same poles will repel (or push away from) each other, while opposite poles will be attracted to each other.

How do magnets work for dummies?
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.
