GCSE Science Double Award Coursework: To find out how the positioning of a solenoid (wire that has been coiled) on a metal core (iron core in our case) affects the strength of an electromagnet

Aim:

To find out how the positioning of a solenoid (wire that has been coiled) on a metal core (iron core in our case) affects the strength of an electromagnet.

Predictions:

I think that the positioning of the solenoid (tightly wrapped coils of copper wire) on the iron core will not have any affect on the strength of the electromagnet, so when the solenoid is placed in the centre or on one of the two sides equal amounts of iron filings will be attracted to the electromagnet.

Scientific Explanation:

Hypothesis: The reason why I think the above will occur is because the positioning of the solenoid on the iron core will not change the magnetic field at all. The only variables that would change the magnetic field would be: current, material of the core + solenoid, how tightly the coils of wire are coiled and the thickness of the crocodile clips (more/less resistance).

Altogether this was a successful experiment because not only was the aim met but also the hypothesis was proved to be correct and most of the results were also reliable except for perhaps that one set mentioned above.coce cer sececew orce cek ince foce ce;

    I will be finding out if the number of coils has any effect on the strength of the magnetic field of my magnet when I test it with weights. From the scientific knowledge above, I have already proved that the more coils there are and the closer they are together the larger the magnetic field strength.
