/diy/ - Do It Yourself

In public middle school, about 6th-7th grade, in eastern US in the 1990s we had to build a small motor in science class. It was just one of those shitty ones similar to this image, but we had to learn all about motors and the general science behind it.

90% of the students in my class completely forgot it by the following year. The only thing people remember is dissecting fetal piglets. lol

It is a linear motor.
