# Electromagnets

Describe the magnetic effect of an electric current (a current-carrying wire produces a magnetic field), and investigate how the strength of an electromagnet depends on current, number of coil turns, and core material

Builds on: Current, voltage, and what they measure (hard, https://ai.page/c/current-voltage-and-what-they-measure/en.md), Magnetic Fields (hard, https://ai.page/c/magnetic-fields/en.md)
