Doorbell

Curated and Reviewed by Lesson Planet

What are some simple uses for an electromagnet? Scholars explore the electromagnetic circuitry in a doorbell through an interesting simulation. They control the core material, number of loops, amount of current, and strength in a spring. With each trial, the simulator displays a graph of the magnetic field as a function of the electrical current.
