does voltage affect the strength of an electromagnet
The factors that affect the strength of an electromagnet are: Number of coils of wire. Number/voltage of batteries. Properties of the core. Number/voltage of batteries. By using a battery with a greater voltage the strength is increased.n iron core will produce the strongest magnet. By increasing the size of the core you also increase the strength of the electromagnet. Compare the diagrams. Note: Look at the amount of coils, the size and number of the power source.
