Making an electromagnet:
This experiment aimed to investigate the direction and strength of a magnetic field around an electromagnet. To do this 3 differing lengthened solenoids (ranging from 50 to 150 coils) were created and then exposed to an electric current, while a compass was nearby to measure the direction of the magnetic field. From this it was discovered the solenoid with the most coils had the strongest induced magnetic field and surrounding field strength, as a greater electric current was able to flow through the device. Furthermore, it was evident that through altering the direction of the current, we also able to manipulate the direction of the magnetic field. This is further evident through the right hand screw rule, as through it we see that changing a current’s direction, will adjust the direction of the magnetic field.

Making an electric motor:
This activity intended to create a successful working electric motor, as demonstrated through its spin upon exposure to an electric circuit. Upon creating a simple motor through attaching a coiled piece of copper wire to a plastic cup via 2 paper clips, it was placed within a minimum 4v electric circuit, in a bid to spin the copper wire. Upon which it was discovered that due to the current, a magnetic field was created around the loop, magnetising the copper. This caused an attraction between the coil and the magnets, causing it to rotate. The black markings on the wire, acted as a commutator which continuously reversed the current and enabled the coil to maintain spin. Essentially this practical, showed how changing the magnetic flux, produced a force. All of which is supported through the right hand slap rule.
