In this video I experiment with Lenz's Law And Faraday's Law of Induction to generate electricity and magnetic force fields in copper. Check out my sponsor Brilliant for a really fun way to learn! www.Brilliant.org/NightHawk

At 1:37, you said "...there is no attraction, nor repulsion...". Wrong. There is attraction or repulsion, depending whether magnet goes toward copper clad or away. Copper is good conductor and magnet generates eddy current, which in turn produce exactly 'mirrored' magnetic field when magnet approaches the surface of the copper. When magnet going away from the copper, you can feel resistance because then magnetic field 'flip'. Still somewhat 'mirrored', but as a 'negative', or in reverse. When magnet going toward copper, north produces eddy current that produces north pole in copper. When you pull magnet from the surface, north pole produces south pole - which attract or as you said - make a feeling of the resistance. When stationary, no eddy current.

+Bitchy_ Bitch! Could you please refrain in the future form using disparaging language. It does not make you look smarter than others. It only brings negative energy into the conversation, no pun intended. Most people are here to learn new things, not because they already know what is being discussed.

+Ken Bellchambers The eddy currents in the metal happen parallel to the metal's surface, and slow down the magnet only indirectly through magnetic field that they produce directed orthogonal to the surface toward the magnet. So, your analogy with eddy currents in a stream is a bit far fetched, but interesting nevertheless.

Good Milan, i have been doing all kinds of similar tests...in a way, like double electrode dual power source GTAW welding and other ways to manipulate the arc and make it behave the way i want it to involving copper and magnets...why? cause we can and obviously to weld faster.

Bitchy_ Bitch! You aptly named yourself. Are you happy with this attitude? I fight being this arrogant for almost 30 years now and find that I'm happiest in those moments when I truly feel that there's wisdom everywhere. As I write this, irritating pictures of persistent idiots I met yesterday pop up in my mind… how is there any wisdom … sigh, must be a bad day.

Your explanation is incorrect. For every action there is an opposite equal reaction. There is attraction when copper is pulled away == and vice versa. But there is one thing I have always wondered about. Can you read a voltage from the copper plates?

You could've gone just a little bit further with inductance. Say, a moving magnet vs stationary, with a bulb. Then, "faster is brighter", etc. Carry on.

They could make elevator safety brakes like this, without using any actual mechanical brakes, just using blocks of copper on the elevator, and large magnets near the bottom of the shaft.

What if you connected a wire through a diode to another copper plate, then drop magnet on copper plate over and over, to see if you could displace enough electrons from copper plate, to see if it losses values of dampening of a magnet being dropped on it?

Thanks, this is fascinating to watch. One can also use this effect to demonstrate that energy and momentum conservation are separate phenomena. Even though the kinetic energy of the magnet can dissipate completely as heat in the metal plate and the magnet, the metal plate will get the magnet's full momentum and would bounce slightly if it could move in your video.

+roidroid either way would be fine with me. You could wrap the magnet so it didn't have direct contact with the barrel wall. I just want to see the magnet or the copper stop from super sonic speed.
roidroid Day ago
Easier the other way around: Fire a copper slug at a magnet. Magnets can be quite brittle (& sensitive to heat also), and may not survive the gun barrel journey.

Ok, please explain this if you can! You drop the magnet through the tube wrapped in copper wire and the magnet collides into the copper plate at the bottom, however, the other experiments the magnet doesn’t collide into the plate. It appears the example with the tube disproves the previous examples.

Just watch the video more carefully. Pay attention to how the magnet drops onto the copper plate, e.g. in slow motion at 2:36.

"Of course, the electrons were perfectly happy being where they were before the magnet tried moving them around." So, the magnets are big bullies and they don't care what the electrons want. That's really mean.

there is a land speed record for a car, that uses magnets to slow down, i didn't realize that it could have used copper as well to help it to slow down, so ty... they said the magnet was an uber magnet but not a different name... so i assume its like the magnets you bought ...the high powered ones. i tried to find the video again and again, with no success, but thought i'd share.

Enjoyed the video was informative, knowledge shared is a blessing too those with are seeking answers to questions. There are great conversations on this video with great bits of informational knowledge; but, there's some people who are so very Learnid (not sure of spelling here, so those who have greater knowledge please correct if possible), above others people who are working in non related fields or even other intrest are just trying to enjoy an Informative video. We mostly are looking for some information about an issue or item. I really understand why some people get "CRANKY" about another person trying to share information in a self-made video. Mr. or Ms.(What Ever), has a issue in their own lives, (" Mommy and Daddy both tell/told me how Very Much Smarter that I'is ( self example of their personal self) mo better being mo smarter than Everyone Else in dah world; All Others are STUPID PEOPLE who must be unable to learn about IT total meaning of all things that, They Mr. Or Ms.(what ever) only knows about. Bet that (This Person, calling Everyone STUPID CAUSE) has too lie about their own place in LIFE as an Insecure Person. I must ADMIT THAT I AM GUILTY OF CALLING OTHERS OUT AS (stupid ) from time to time. If You continue to repeat what is a LIE and unwilling to understand the Truth, THAT'S STUPIDITY ON YOUR PART, I can we get what were thought to theTruth, I must then state is the Truth. Ignorance is different than stupid. Ignorance is not knowing a fact on a Issue. Stupid is knowing the Fact and refusing to tell the Fact unless you tell the Fact in a lying way to suit your own agendas, fyi Democrats loyalist do this all the time. Life is a Life even before Conception. The Sperm and the Egg are already a live, then Die Off when not used in an X amount of time. But isn't Conception just the beginning of the life of an Idea? Ah look yeap, Ideas spring too Life, so does that Eggs living Yoke (pre-Baby). Any other answer is a Lie ... I had to put 3 periods cause I can't find hugh Period if on this so called SMART PHONE phone. Breakfast is calling me, To everyone God Jehovah says Live Each Other by holding Each Other To the TRUTH IN ALL THINGS. ALL THINGS ARE KNOWLEDGE TO BE FOUND OUT, so seek knowledge and understand what LOVE IS AND MEANS. Blessings to All

Every particle is composed of a north and a south opposing electromagnetic fields. It takes a moment for their alignment takes a moment to happen when exposed to another magnetic field. Think of electrons as tiny magnets with north and south fields rather than as a negatively charged particle.

It looks as if the magnet and nearby metal are in some kind of gluey, highly viscus fluid, opposing any sudden change of movement. This is how scientist of the old age described such phenomena. They told us is school that such kind of "understanding" was primitive but to me it looks just natural. I think Nikola Tesla saw electromagnetic phenomena is such a natural way.
