A permanent magnet changes the flux through coil, generating a voltage that can be read by an analog voltmeter (you can pretend it's a galvanometer). Connect the voltmeter to the coil or to the DAQ ...

Resistive magnets are built in-house at the magnet lab using so-called Florida Bitter technology pioneered by researchers there. Circular plates of copper sheet metal are stamped with cooling holes; ...

Drag racers are constantly searching for ways to either go faster down the quarter-mile or to make those quarter-mile blasts become more consistent. There are plenty of ways to make more horsepower ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

We can make electricity by constructing a basic generator. This would allow us to change kinetic energy into electrical energy, which in turn could be stored as chemical energy in the battery. The ...
