This demonstration shows that when an electrical current is sent through a solenoid, it creates a magnetic field. When that electrical current is sent through at the resonant frequency, it causes the magnet to oscillate.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Hang the spring from the ring stand. Attach the pendulum mass to the end of the spring. Attach the magnet to the bottom of the mass. Align the solenoid below the spring system. Adjust the height so that the magnet is just above the solenoid. Set up the webcam with the projector to view the system.
Connect the function generator to the solenoid. Choose the resonant frequency and sine wave.
Turn on the function generator. The spring system oscillates.
Notes:
This will only work at the resonant frequency.
