Electromagnetic Induction and Faraday's Law

- This is an improved version of my earlier video on electromagnetic induction, ( • Electromagnetic Induct... ) the generation of an electric field by a changing magnetic field. Electromagnetic induction is demonstrated using a coil, galvanometer, and a bar magnet

Prof. Melloch,
Thanks for posting this well explained demo. My only gripe is that Lenz's law could have also been easily demonstrated if the direction of the coil's winding was obvious. Instead of using the wire itself to hold the coil together, transparent tape could have been used, leaving the ends of the coil free, and the winding direction clearly visible.
If I watch closely, the coil seems to be wound clockwise going from the right lead (connected to red) and coming out of the left lead (connected to black). When the N-pole is plunged in, the needle deflects in the +ve direction, meaning a +ve current is going from the red terminal to the black terminal within the μ-ammeter (through its shunt resistance), and in the external coil, +ve current goes in from the left (black) lead to the right (red) lead, i.e. in an anti-clockwise direction, creating a N-pole projecting outwards. So, this is also a demonstration of Lenz's law.
Simplistic and well performed! Keep the good work up and never stop educate "the masses". You are an oasis in the swamp TH-cam garble and misinformation and I thank you for your work!!
Thank you for your kind words about the video.

can a battery work ?
Or the measurements of it and strength.

Can you help me out please? I am working on this for a science fair project. Can you tell me which type of magnet that is and where you brought it at?
+Phil Uppster Here is a link to the magnets www.pasco.com/prodCatalog/SE/SE-8604_bar-magnets-2-pack/index.cfm
Note any magnet will work, but the stronger the magnet the greater the effect, such as using an neodymium magnet.
Make sure you use a galvanometer as your ammeter,

Michael please help meI tried to do this experiment but couldnot. Please tell the wire gauge, magnet strength and tell me do I need to remove the insulation ( enamel of the wire)
The wire gauge should not matter. Only remove the enamel at the two ends so that you can make electrical contact. You do not need an especially strong magnet. You need a meter that will be responsive to a pulse of current like a galvanometer.

Interesting, what type of copper wire are you using? Is it pure copper wire?
It is magnet wire, so it has an enamel insulation that needs to be scraped off at the ends to make electrical connection. It was probably 24 Ga, but I don't remember. But it should work with any diameter wire. The smaller the diameter would add some resistance that might reduce the current.
@@electricandmagneticfields2314 thank you so much for your information.
Cool
Can we use magnet like neodium for the same ?
Any magnet is fine. The stronger the magnet the larger the current generated for the same movement of the magnet.
@@electricandmagneticfields2314 thank you for the guidance . Found your video really helpful
if i want to learn more about the equations and how to understand them, what subject should i go about learning. Physics? Algebra? both? Just a man from the hood trying to educate himself, thx.
Either going into physics or electrical engineering is a path to the equations. Going into electrical engineering will expand your job opportunities.
👍
Will a multimeter work? Pls reply :>
No, you need to use a galvanometer.
واو
اني شورطني وانزل للتعاليق🤣🤣🤣
the actual experiment has been done using a galvanometer, so can we do it using an ammeter, too?
The ammeter will not be responsive to the pulse of current you are generating. So you need a galvanometer.

Good day sir, im having problems doing that experiment, you see, i used a #22 solid copper wire and coiled, then i used strong disc magnets. But when i tried to see if there's current, there's no deflection in the galvanometer, even though i tried to pass a magnetic field to the conductor. Pls help (sorry for bad english)
Does your copper wire have insulation on it?
what insulation? the rubber covering the wire? or the thin coat in the wire? i removed the rubber, but not the thin layer coat
I am not sure what you mean by rubber on top of a thin coat. The wire needs to be insulated otherwise you effectively have just one turn. The only place you need to remove any insulation is at the ends so that you can make electrical contact.
try to burn the two ends of the copper wire with fire for a few seconds.
I m a teacher of physics, yesterday I did same experiment at lab but there was no any deflection in galvanometer . I removed insulation of the wire at ends .....can u tell me what was the problem behind this?
