The uses of magnets in everyday life extend far beyond what many might expect. From fridge magnets holding up shopping lists to speaker magnets delivering sound and hard drive magnets storing critical data, magnets are everywhere. They are integral to household devices, electronic gadgets, ...
Making a Dimmer Switch is another way to process electricity that always makes me smile. When the kids make a dimmer switch, they will learn how magnets work together to create motion and light. They can then use this knowledge to create their electromagnets!
They each use electromagnets, devices that create a magnetic field through the application of electricity. Wrecking yards employ extremely powerful electromagnets to move heavy pieces of scrap metal or even entire cars from one place to another. Your favorite band uses electromagnets to amplify the ...
The theory uses a curved coil of wire as an inductor. A capacitance plate, which can hold a charge, attaches to each end of the coil. As electricity travels through this coil, the coil begins to resonate. Its resonant frequency is a product of the inductance of the coil and the ...

Inductive coupling uses magnetic fields that are a natural part of current's movement through wire. Any time electrical current moves through a wire, it creates a circularmagnetic fieldaround the wire. Bending the wire into a coil amplifies the magnetic field. The more loops the coil makes...
