Day 1

  We were briefed on our project at the NTU lab, where the electrical equipment is kept. There, we constructed a basic DC motor, using some wires, a strong magnet that could potentially screw up your phone's memory, a think piece of iron rod which is coiled around tightly using the wires and a AA battery. The circuit formed a small electromagnet, which, when put close enough, interacted with the permeant magnet and caused the electromagnet to sway back and forth for a shot while after the circuit was closed.

  Due to the fact that the motor we made was a very basic one, it did not flex that much. After our break, we proceeded to build our next DC motor, This time, a more complex version, which when built properly, will act like a real motor. Comprised out of more than 5m of wire, a partial metal loop, a metal shaft, 2 metal plates and some plastic electrical components, it would create a moving central shaft, just like a real motor. The most important step was to coil the wire around the base of the partial metal loop. This, when connected to a power source, would create a electromagnet.
