Question

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

Answer 1

1. Increasing the current passing through the wire wrapped around the core of the electromagnet will increase the magnetic field strength. This is because the magnetic field is directly proportional to the current flowing through the wire.

2. Increasing the number of turns of wire around the core of the electromagnet will also increase the magnetic field strength. This is because each turn of wire adds to the magnetic field produced, so more turns will result in a stronger overall magnetic field.
