MAKE presents: The Inductor

The deceptively simple wire coil that proves incredibly useful in the world of electronics - the inductor's ability to store energy in an electromagnetic field is the key to making transformers, electromagnets, and many more components. It truly is an awesome device!

This gentleman is really wonderful........!!!!!!!!

What are those little spikes at the start and end of the power on/off starting at 6:05 and more prominent at 6:16? What would happen if we released those into a couple of rectifying diodes and on to create negative resistance in a lead acid battery?

I have EXACTLY the same pen ;D

Colin is just extremely good in explanations. Loved his tutorials and funny explanations. Of course his humor is always on good level! :)

A capacitor is reluctant to change voltage, and stores the charge as a potential differential between insulated plates. An inductor is reluctant to change current, and stores it as a magnetic field.

A coil can act like:

...an electromagnet like on a crane in a scrapyard.

...a flywheel as in a tank circuit.

...an inductor as a transformer.

...a short in DC.

What's with the anaglyph titles!? Nice!

[Wayne Holliday]

Wished I had this stuff available to me when i was doing my pHD! lol

Mr. Cunninghum, it would kill to smile a little. I mean it's just about stretching your lips a little....... :-)

[DivineOwnageEVE]

That looks like the waveform for a capacitor. An inductor response looks much different.

This guy is a Rivers Cuomo wannabe. Can't people be original these days?
