Question

A student is creating an electromagnet for an investigation. Which feature of the electromagnet will least influence the magnetic force?

Answer 1

The material used in the core of the electromagnet will least influence the magnetic force. The core material can affect the strength of the magnetic field to some extent, but other factors such as the number of turns of wire, the current passing through the wire, and the shape and size of the electromagnet will have a greater impact on the magnetic force produced.
