Magnetic Fields 'Bending' Light Paths

I show you how a magnet and ferrofluid can be used to change the orientation of iron particles. The iron nanoparticles can reflect LED lights. This "bending of light" is most likely specular reflection, however there has been no definitive proof. Though this device does not necessarily show magnetic fields, it can show you the effect of the magnetic field on the position of the iron particles.

It isn’t an action lab video without a “woah, that is *so* cool”

The fact that he could see the nails in the walls is really cool!

The timing was perfect I was just playing with magnets when This was uploaded

I'm always surprised as to how his garage looks so white and clean after all these years of doing weird experiments in there. I mean the garage door, the floor & walls look almost pristine new condition after all the burning, combustions, and general banging stuff around in there...kudos!

I love how you explain everything in a simple manner.

The sun may turn into a red giant, and black hole may evaporate away due to Hawking radiation after 10¹⁰⁰ years, but my man will never run out of ideas.

*POV:* You’re in one of Magneto’s dreams.

sometimes i forget how cool you are and the cool videos you have been making consistently for the past 3 years and more. thanks for putting the physics from lectures and notes into visual demonstrations!

what a beautyful thing is magnetic field <3

Magnet: I saw some aura around me🙄🙄
Flame: Where did it happen.😐
Magnet:At the action lab😃
Flame: I was once blackened where you were enlightened😑😑
Magnet:It's irony😂😂

Just so anyone can understand: There’s a difference between bending a light ray without a change of medium (n1=n2) as in actively changing a photons path by some force acting on that photon and changing the path of particles with light reflecting on them. Therefore you’re not bending light in the literal sense. The only force that can do that is gravity.

reminded me a physics experiment back from highschool. the setup consisted of a glass sphere with vaccuum inside, as well as a piece of coal in a circuit acting as resistence. over it was a cone with hollow tip, so when the coal was electrified, it generated a beam of light that was actually purely negatively charged.

The real show was when two hugeass electromagnets were also powered up, which ultimately curved the beam of light in the vaccuum, bending it all the way into a coil, if my memory didn’t exaggerate the visual in the last 20 years.

I thought it was going to be that, but still thanks for rehashing those fond memories from the lab. There probably is a standard name for this experiment device and you - and anyone else reading it - probably knows. but given your content, I’m sure it would be cool both for watching and creating.

Great job!!!! Another interesting and informative video! I love when you put the paper on the wall to find the nails. Thank you so much.

Love your channel. I wonder if you've seen Kenneth Wheelers work with magnetic fields. He's probably one of the worlds leading experts on magnetism. Literally wrote the book on magnitism. He makes Ferrocells using optical flat glass. I made one using window pain glass cut in 2 circles. Its so neat to be able to see the field in this way.

This was a mash of theoria apophasis and braniac. Thank timm vanderelli for this invention.

Can't wait for a video title about "How Fire gets its shape" or how much of a sphere the earth is

[maryroberts]

I like the way he says "You..." as if I'm following along at home with my own ferrofluid and LED lights - just like this is a cooking show. It makes me feel like a could be a garage physicist too.

Probably the BEST explanation for magnetic field!
