Day 100: Electric Motors Day 2

Today in AP Physics 2, the construction of electric motors continued. Today’s focus was building the commutator, analyzing it, and appreciating the role it plays in changing the poles of the electromagnet as the armature rotates. For many students, this was their first time soldering. After a little guidance, every group successfully soldered the wires from the electromagnet to the tin armature.
