Electromagnetics wrap up session
In The top photo, I am showing the boys some of the characteristics of transformers on paper. The center photo shows the DC Permanent magnet motor operating as a generator to light a small light bulb. The bottom picture shows us measuring the RPM of one of the motors with a laser beam RPM tester. How fast is that motor spinning? There must be some mistake!
