Earlier today, engineering intensive students learned how to use electrical currents in order to create propulsion. The schema for the activity revolved around the construction of a Beckman motor- the current goes around the coil so that it points one direction at one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction. The result is the world’s simplest motor.
