Using a simple model of an electromagnet, describe the factors that increase the magnetic field strength of an electromagnet.(2 points)
1. Increasing the number of coils in the wire: When more coils are added to the wire, it increases the amount of current flowing through the wire, which in turn strengthens the magnetic field produced by the electromagnet.
2. Using a stronger power source: Increasing the voltage or current of the power source used to energize the electromagnet will increase the magnetic field strength. More energy means more magnetic force generated by the electromagnet.
