Excellent demos. I especially enjoyed seeing the magnetic flux lines superimposed. I would have loved to see the final set up with TWO sets of magnetic flux lines reflecting the inverted pole orientation.
THANK YOU!!!! I've been looking all over to explain this to my students and this easy demonstration can easily be done in class and is VERY straight forward. THANK YOU!!!
Very good explanation. Rafael, Thiago, Amanda, Jihun, Lais, Maria and Julia congratulate you for it. Changed their way to understand the subject. Thank you!
Beautiful We need these simple explanation with experiments Thank you Michael Faraday dropped a lodestone unto a hollow bamboo wound with copper coil connected to current detector and current detected Madam stood up "Sir what is the use of this? "Faraday took the child of a lady and asked "Madam could you tell me what'll be the use of this newborn baby? That baby is Electricity
So is there a limit to amount of electricity you can achieve? For instance if you attached a rocket motor to that magnet and shot it through the coil super fast, could you produce a lot of power or is there something that would eventually limit the output regardless of the speed of the magnet?
Excellent explanation. The only criticism I have is that you have not established the induced current is opposite to flux change. Moreover, the direction of the galvanometer is also depending on how you connected the wires. You may use a battery to show the direction of the current first. Just my two cents.
If the solenoids were put side by side, instead of on top of each other, and the current was turned on for the first solenoid, would there still be a deflection in the magnetic field, and therefore a current measured for the second solenoid?
That is how speakers, microphones and pickups work. But what about electric motors? All explanations I see attribute the torque to magnetic attraction/repulsion. But is that really true?
Thank you one humble question In the century that Sir Faraday exhibited this what was the current measuring instrument or was the galvanometer invented then ?
So, does the magnetic flux change the electron's magnetic field which then changes the direction of the current? I mean does the outer magnetic field that acts on another loop wire change the electrons magnetic field and that changes the current direction. Is that correct ? Does this work with a straight wire or it we need a loop to work ? Thank you a lot !
Nice demonstration, but a terrible equation in the end! It is not about PHI, it is all about the CHANGE IN PHI (8:19). By the way, he doesn't EXPLAIN this relationship. He only shows you that in practice it is that way. Nothing more.
This is actually the best. The new syllabus is finally making sense!!
Excellent demos. I especially enjoyed seeing the magnetic flux lines superimposed. I would have loved to see the final set up with TWO sets of magnetic flux lines reflecting the inverted pole orientation.
1:10 - "The maggot has a magnetic field around it!" - Answers all my questions thank you!
THANK YOU!!!! I've been looking all over to explain this to my students and this easy demonstration can easily be done in class and is VERY straight forward. THANK YOU!!!
I love this content! I can see how Faraday's and Lenz's laws work clearly here! Thank you so much for the explanation and demonstration.
First Year UNSW: *Reads Textbook* Ah okay.
*Watches High School Physics Explained* I get it now.
Thank you!
Msg me first via Facebook or twitter. Need more details
Excellent and thank you oh if our children in India could be taught this way Theory with practice is the best method in any subject
Thanks
True
Thank you, sir. You are doing a great service to those of us who want to understand this and other physics topics!!!
Such demo sheds light on dry equations... thanks
Very good explanation. Rafael, Thiago, Amanda, Jihun, Lais, Maria and Julia congratulate you for it. Changed their way to understand the subject. Thank you!
This is really an amazing demonstration of Faraday's law! please keep up this effort
Thanks
Great professor. Thanks so much for sharing your passion.
Great video - very clear

State of the art clear demonstration of electromagnetism principle! Thank you very much.
This was great
Brilliant video! Thank you for this!
Great explanation. Thank you.
helped in understanding Faraday's Law of Induction. Thank you.
Helpful video, thank, I learned alot
Thank you sir for good information
Soooooo helpful!! Thank you Paul, I appreciate you.
Glad it helped. 👍
So is there a limit to amount of electricity you can achieve? For instance if you attached a rocket motor to that magnet and shot it through the coil super fast, could you produce a lot of power or is there something that would eventually limit the output regardless of the speed of the magnet?
It is proportional to the force pushing the magnet through. So no
Great video, thank you!
Very nice explained

Nice and detailed explanation, this what we are mixing in science education in west Africa sub region.
Hi.
The video is okay but when you turn the magnet around (2:01) the south is not facing outward but downward, seen in relation to the coil.
This was fantastic, thank you!
If the solenoids were put side by side, instead of on top of each other, and the current was turned on for the first solenoid, would there still be a deflection in the magnetic field, and therefore a current measured for the second solenoid?
Yes, as long as there is an iron core connecting them. This causes flux linkage.
So captivating
Hi can you tell me how many turns you have on your coils and what voltage did you use?
Thanks!! It really helped.
Thank you🙏💕 it really helped me.
Nice!
Nice I get this phenomena
very good
Anyone know where those ammeters can be purchased?
Very good explanation thank you sir.
You are welcome
Thank you so much for this video.
That is how speakers, microphones and pickups work.
But what about electric motors?
All explanations I see attribute the torque to magnetic attraction/repulsion. But is that really true?
Great explanation. Where could I buy a similar setup to use it in my classes?
What if you have two magnets one on the outside and one on the inside?
what is the name of the thing that is showing the voltage?
Thank you one humble question In the century that Sir Faraday exhibited this what was the current measuring instrument or was the galvanometer invented then ?
How much turns of wire used in demonstration
So, does the magnetic flux change the electron's magnetic field which then changes the direction of the current? I mean does the outer magnetic field that acts on another loop wire change the electrons magnetic field and that changes the current direction. Is that correct ? Does this work with a straight wire or it we need a loop to work ? Thank you a lot !
A big thanks and subbed!
Thanks for the sub!
thanks
Thanks.... I would like to learn how to use the equation to gauge how many turns needed to make a: low pass coil/ mid/& high..can you help me please?
Explain polarity of 4 coils when magnet moves across all 4
can you make an expermient of inserting an insulator between two capacitor plates... PLS🥺
great video and channel!
Thankyou
Thanks sir! What school do u teach?
I teach at Macarthur Anglican School
why do the radial magnetic fields not used in AC Generators
Beautiful
Good
Very nice sir
Thanks and welcome
👏💕
This video is golden. You can't find a better balance of simple and comprehensiveness.
Thanks
PCSI 1 >> PCSI 2
1 magnetic field + 1 magnetic field = 1 magnetic field.
