1. Electric current creates a magnetic field that can generate a magnetic force. (i.e. doorbell, solenoid +compass, wire)
2. If you move a magnet in the presence of a wire, electric current will start to flow. (Hand crank generators, online phets) Next, we performed our motor and speaker lab in which we built a prototype motor and speaker from a magnet, wire, paperclips, a block of wood, and a battery.
After that, we went onto take our electromagnetism test.
RWC:
In order to start a leafblower, you must pull on the cord to start the engine. This causes the magnetic fields within the leafblower to begin repelling and attracting each other. This is how many machines nowaadays function.
