Electomagnet Investigation

The electromagnet we will be making is a very primitive one compared to that of the complexity of modern electromagnets found in machinery, but the way it works is almost identical. Electromagnetic technology is extremely complex and because it is an electromagnet, the higher the current, the stronger it becomes, and with this an electromagnet can become incomprehensively strong. Such an example is that used in theme park rides to stop moving parts etc. these electromagnets are in fact so strong that when uncovered, if you were to stand with a spanner in your hand 10 metres away, it would pull the spanner out of your hand along with the rest of your arm! To understand fully how an electromagnet works read on…

When an insulated wire is wrapped around some form of iron, nickel or cobalt core, whether it be a nail or a u-shaped core, and then attached to a power supply it creates an electromagnet capable of picking anything from the size of a paperclip right up to anything as big as a car and bigger! Obviously such a primitive elect

My prediction is that when the current is increased in turn so does the strength of the electromagnet. I believe this because an electromagnet needs an electrical input in order to create a magnet, so logically if that electrical input is increased then it becomes stronger.

4: A fixed amount of nails will be poured over the electromagnet with the power switched on

There are four main factors that affect the strength and size of this field:

We will make sure that there is no bare insulation or any water near any electrical equipment to prevent electrical faults and dangers
