Investigating Electromagnetic Induction (Lenz's and Faraday's Laws)

In this video we look at what happens when a magnet falls though a coil that is attached to light emitting diodes. The change in magnetic flux in the coil induces a current that lights the LEDs. This is known as electromagnetic induction and can be described qualitatively with Lenz's Law and quantitatively with Faraday's Law.

How do i make the led backward biased

[@reiotech997]

Very good explanation 🤗

[@electricandmagneticfields2314]

Thank you 🙂

2:39 that's not the symbol for a resistor. it looks closer to an AC generator. boo.

[@ripper5941]

It was very wise to use a diode to demonstrate the Lenz law

[@electricandmagneticfields2314]

thank you

[@adnanfatchurrachman2665]

please ask sir, what do you use for the coil?

[@electricandmagneticfields2314]

This was a rare case where I didn't build everything, that is wind the coil. I used one I already had. Here is the link to it but it is expensive, www.pasco.com/products/lab-apparatus/electricity-and-magnetism/coils-and-cores/se-8653 You could probably rig a drill and wind your own coil.

Nvm got it

[@electricandmagneticfields2314]

Great!

This is only magnetic induction, what about the other form of induction (capacitive)?

please use a capital I to denote current. the lowercase I is used in special cases.
