Lenz law explained

From my first video demonstrating Lenz's law, many people asked for it to be explained.

Magnetic fields from strong magnets can create counter-rotating currents in a copper or aluminium pipe. This is shown by dropping the magnet through the pipe. The descent of the magnet inside the pipe is observably slower than when dropped outside the pipe.
When a voltage is generated by a change in magnetic flux according to Faraday's law, the polarity of the induced voltage is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant. The direction of an induced current can be determined using the right-hand rule to show which direction of current flow would create a magnetic field that would oppose the direction of changing flux through the loop. In the examples below, if the flux is increasing, the induced field acts in opposition to it. If it is decreasing, the induced field acts in the direction of the applied field to oppose the change.

Great way for new students, thank you good sir.

[LibertyEver]

Very good demonstration and explanation of Lenz's law.

[sohammajumder]

My whole concept is clear thank you sir

[Azza]

very interesting. May I ask what that green sheet is called? I enjoyed seeing those waves

[ScottAllen]

Learned a little. Why was a field created opposite the magnet?

[keneatstheworld]

It can be weight also
(I'm using the word weight because of the involvement of gravity)
It can be magnetism also
But I think that here magnetism is more effective in slowfalling.

Try with the same weight and size of magnet. I can see there is resistance with the magnet touching the sides of the tube . Dripping outside the tube there is no physical restriction that's one reason for it to drop faster . Now don't get me wrong I am not doubting that it may be inducing a magnetic field. But I would like to see examples of magnetic and none magnetic that are the same size and weight.

Can this energy its putting off be harnessed in anyway

[NoosaHeads]

Not an explanation - this is a demonstration and now the viewer would like an actual explanation. However, the explanation is quite complicated and involves charge, conservative of momentum direction of field flux, velocity and mass.

[aarushidubey]

And the phenomenon is electromagnetic damping

I think you are father of johnny sins 🤔🤔

Thank you very much!❤❤
God bless❤❤

Remember Jesus loves you died for you and wants to know you❤❤❤Repent, god bless❤❤❤
