Physics Investigation Electromagnets Aim My aim for this experiment is to find out what kind of effect the strength of an electromagnet has if the number of turns on the coil and the current going through the coil are increased. Background Electromagnetic induction is the idea that magnetism can travel from one object to another even though they are insulated. A greater number of coils in the solenoid around the core will increase the strength of the field produced by that electromagnet. This is because the amount of power given to the solenoid and core is increased so the core receives an increase in power, so the domains become aligned strongly, and more domains become aligned. In addition, with an increase in coils the coils cover a greater surface area of the core. This means the coil covers more domains and therefore more domains are influenced. Each turn has it's own field so more turns...
