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
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
Fun Fact 11: There are certain types of metals which can become
permanent magnets. These varieties include metals such as cobalt, nickel
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
