Explains the theory of electromagnetism by building slowly from a simple bar magnet to a completed electromagnet made from simple home materials.
A very basic film about what makes electromagnets work, and how you can make one yourself. Designed for elementary school students (in science class of course), this takes 2 kids wanting to know why their doorbell don’t work. Luckily, big brother is around to show us basic elements of electricity through experiments. Very good to what it’s accomplishing here.
