Question

Using a simple model of an electromagnet, describe the factors that increase the magnetic field streng of an electromagnet . (2 points)

Answer 1

1. Increasing the number of turns of wire in the coil: The magnetic field strength of an electromagnet is directly proportional to the number of turns of wire in the coil. By increasing the number of turns, more magnetic field lines are generated, resulting in a stronger magnetic field.

2. Increasing the current flowing through the wire: The magnetic field strength of an electromagnet is directly proportional to the amount of current flowing through the wire. By increasing the current, more electrons flow through the wire, generating a stronger magnetic field.
