... Physics coursework Aim The aim of this investigation to see the strength of an electromagnetic by varying many variable, and seeing how this affects the performance of the electromagnet. Variables there are many variables which can increase or decrease the magnetism of the electromagnet. these are the following variables:- Number of coils:- the more the number of coils the more the electromagnetism because, each coil creates a magnetic field. So the more coils the more magnetic fields thus the magnetism increases. Current:- this will increase the number of electrons going around the electromagnet therefore increasing the amount of magnetism. Distance:- the distance the electromagnetic is away from the target object will also decrease the magnetism. Type of iron core:- the material of the iron core could dramatically change the amount of magnetism. Length of nail:- The length of the nail will be a controlling factor, because the longer the nail is the more coils can be fitted around the
