Mon. Week 12, May 12: Applications of Magnetic Force

On this day we set out to learn how the properties of magnatism that we learned from the previous class could be used in practical situations. One of these applications is the motor, a device that converts electrical energy into rotational motion. The motor is the heart of all automation and motion in electric devices.

The first exercise we performed was energizing a small motor and seeing how changing the magnetic field through it affects its motion.

After developing an intuitive understanding of how the orientation of the magnetic field affects the torque on the coil windings, we then set out to make our own motors from just wire with a current passing through it and a magnet.

After taking some time to make various adjustments, the simple motor proved to be operational and the exercise was a success.
