WebWhat is a magnet? Magnets have a north pole and a south pole. Opposite poles attract each other. But two north poles will repel each other, as will two south poles. Magnetic … WebGravity. The force that pulls things to the centre of Earth (and other planets) is called gravity. Gravity also holds Earth and the other planets in their orbits around the Sun. The force of gravity also exists on the Moon but it is not as strong as it is on Earth. This is because the Moon is much smaller than our planet.

WebThe force due to gravity follows from the interaction between the Earth's mass and any other body that happens to be nearby (the effect extends far beyond the Earth to the Moon and beyond). Unlike gravity, magnetism doesn't work for anthign with mass. Magnetic forces only occur between specific materials (mainly iron and certain iron alloys). WebThere are a number of elements that are attracted by magnets, commonly referred to as ‘magnetic’. These are the same materials that can be magnetised to create permanent magnets, Here you can see a list of magnetic elements and minerals: Magnetic materials are categorised as magnetically hard, or magnetically soft materials.
