Len'z law and a interesting video

In summary, The video discusses Len'z law and the interaction between a magnet and an aluminum cylinder. The speaker mentions that the magnet is pushed down by the cylinder, but does not provide details about the speed. The speaker also poses questions about the phenomena and whether the magnet's speed is affected by the cylinder's presence, as well as the presence of induced current.

Please what this.
This video will describe Len'z law from 0:00 till 1:25
You can skip till 1:25 and see the interesting part to understand the following question.


* Is the aluminum cylinder pushing the magnet down with a higher or lower or the same speed at the initial speed passing only the copper pipe?
The guy says it pushes the magnet down so no details were given about the speed.
Why does this very interesting phenomena happen?!
And do you think when the magnet is approaching the aluminum cylinder its becoming slower and slower because a force is repelling in? Or nothing happens until the magnet passes the cylinder?!

Ow yea and do you think current is still induced with the presence of that aluminum cylinder?
 

FAQ: Len'z law and a interesting video

1. What is Len'z Law?

Len'z Law is a physics principle that states that when a conductor is placed in a changing magnetic field, an electromotive force (EMF) will be induced in the conductor, causing a current to flow. This is also known as electromagnetic induction.

2. How does Len'z Law relate to Faraday's Law?

Len'z Law is a consequence of Faraday's Law of induction, which states that a changing magnetic field will induce an electric field. Len'z Law specifically describes the direction of the induced current in the conductor.

3. What is the significance of Len'z Law in everyday life?

Len'z Law is the underlying principle behind many modern technologies, such as electric generators, transformers, and electric motors. It also explains how induction stovetops work and is used in magnetic braking systems in trains and roller coasters.

4. Can you give an example of Len'z Law in action?

One example of Len'z Law in action is when a magnet is dropped through a copper pipe. As the magnet falls, it creates a changing magnetic field in the pipe, which induces a current. This current then produces its own magnetic field, which opposes the motion of the magnet, causing it to fall slower than if it were dropped through air.

5. Is there a visual representation of Len'z Law?

Yes, there are many videos available online that demonstrate Len'z Law in action. One interesting video shows a magnet falling through a pipe, as described in the previous example. Another video shows how Len'z Law can be used to levitate a magnet above a superconductor. These videos can help to better understand the concept of Len'z Law and its applications.
