Anna Hamilton 27/01/2005 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...
