Fun Fact 2: Everything on Earth consists of atoms. Millions of atoms make up the tiniest of things. Each atom contains a centre point known as the nucleus. The nucleus contains small particles called protons and neutrons. Constantly spinning around the nucleus are electrons which are much larger particles than protons or neutrons.
Fun Fact 3: Electrons are contained in a shell; the inner shells contain less electrons than the outer shells. The electrons spin constantly around the nucleus but they never touch the nucleus.
Fun Fact 4: Electrons are attracted to protons, as they too, produce an electric charge. In return, protons are also attracted to electrons. Electrons are negative, symbolized by - sign and protons are positive, symbolized by + sign.
Fun Fact 5: Protons and electrons are more attracted to one another the closer they are; therefore, the protons closest to the nucleus will be the most attracted.
Fun Fact 6: It is at this point that the outer electrons can move from one atom to another as the outer shells are forced out. This is how electricity is produced.
Fun Fact 7: As an example, we will consider the charged particles which are released from a battery. Upon being released, they are often carried through a wire. It is at this point that a magnetic field is created around the wire.
Fun Fact 8: If the wire transporting the electrons is wound round a certain type of metal, such as iron, the iron will become magnetic. This can now be called an electromagnet.
Fun Fact 9: The more times that a wire carrying electrons is wound around a type of metal such as iron, the stronger the magnet will become.
Fun Fact 10: Electromagnets attract other parts of metals which means they can be used to carry out huge and important jobs which would otherwise prove difficult to man. This may include lifting up an entire vehicle.
Fun Fact 11: There are certain types of metals which can become permanent magnets. These varieties include metals such as cobalt, nickel and iron.
Fun Fact 12: Electromagnets are used in very important devices such as door bells where the magnet can be turned on and off. They also enable devices to function, for example; starting a car
Fun Fact 13: There are two different ends to a magnet which are known as the 'magnetic north pole' and the 'magnetic south poles'. The name for both ends is simply known as 'the poles'.
Fun Fact 14: MMagnetic energy is strongest at the poles (either end of the magnet). As each end is different, they attract one another. You can test this by placing two magnets next to one another. You will see that they will attract by one of the south poles and one of the north poles. If you try putting either two south poles or two north poles together, you will discover that they repel against one another.
Fun Fact 15: Metals which are permanently magnetized, do so because the electrons inside the atoms all spin in the same direction resulting in little electromagnets!
