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

[@reiotech997]

Very good explanation 🤗

[@electricandmagneticfields2314]

Thank you 🙂

[@h7opolo]

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

[@ripper5941]

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

[@electricandmagneticfields2314]

thank you

How do i make the led backward biased

[@P.M.V.GopalaRao]

what is the no. of turns of coil ? and what is strength of magnet to light led bulb?

[@electricandmagneticfields2314]

I purchased that coil from a company called Pasco, www.pasco.com/products/lab-apparatus/electricity-and-magnetism/coils-and-cores/primary-and-secondary-coils#desc-panel It does not say how many turns on that outer coil. I used several rare earth magnets stuck together. So the strongest magnets I could find. Probably similar to these, www.amazon.com/TRYMAG-Magnets-Neodymium-Refrigerator-Whiteboard/dp/B0C5MBX588/ref=sxin_16_pa_sp_search_thematic_sspa?content-id=amzn1.sym.76d54fcc-2362-404d-ab9b-b0653e2b2239%3Aamzn1.sym.76d54fcc-2362-404d-ab9b-b0653e2b2239&crid=26Y2WC9W32OA4&cv_ct_cx=rare%2Bearth%2Bmagnets%2Bstrong&dib=eyJ2IjoiMSJ9.zRXM9KvWwMREIOAkiiQgjfD6czymSvPDDp9zr0BJsSiLiscEfpX8pS5LBFOlUzmZ.FQ-2MCjic5wM2GYwDOheqk9G6s9yEkQhsp8pzbNUS90&dib_tag=se&keywords=rare%2Bearth%2Bmagnets%2Bstrong&pd_rd_i=B0C5MBX588&pd_rd_r=05ccd503-66da-44d1-8911-30f6078369f0&pd_rd_w=LqQSH&pd_rd_wg=130mW&pf_rd_p=76d54fcc-2362-404d-ab9b-b0653e2b2239&pf_rd_r=H3ARAGVWZEV3V31CG56X&qid=1731328113&sbo=RZvfv%2F%2FHxDF%2BO5021pAnSA%3D%3D&sprefix=rare%2Bearth%2Bmagn%2Caps%2C141&sr=1-2-6024b2a3-78e4-4fed-8fed-e1613be3bcce-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9zZWFyY2hfdGhlbWF0aWM&th=1

[@MasterIvo]

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

[@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.

[@embla5223]

cool!

[@electricandmagneticfields2314]

Thanks!

[@h7opolo]

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

[@SaminaShereef-ij4bd]

Nvm got it

[@electricandmagneticfields2314]

Great!
