Hi! Thanks for watching. Comment if you have ideas for further testing of the monitors - or something else the monster magnet should meet... I would like to test if X-rays/bremsstrahlung escapes when the electrons are focused down to a tiny spot on the CRT screen by a magnet. Does anyone know how to easily detect soft X-rays below 30 keV? They are not ionizing enough for my detectors.

What I'm wondering about the 22" monitor from 2009 is if you put a plasma globe near the back where the fluorescent backlight tubes are, what will happen to the video? Because I know that fluorescent tubes are lit by microwave radiation and plasma that comes off a globe. Maybe make a video about that?

Expect the CRT to be sort-of trashed after you do the experiment. Focusing the electrons to a single point will most likely burn the phosphor in that place (unless you turn the brightness really low).

So he was roughly 10 feet away from the monitor with a magnet and it was powerful enough to distort the image. That’s absolutely INSANE!

The magnetic fields in the NMR room back in college were absolutely insane. You had to leave your wallet near the door because they could wipe your cards easily. Monitors 20-30 feet away from the magnets would show color distortion all the time while you used it. The room had an emergency blower system that could completely vent the room and replace the air in under 30 seconds (and it was a BIG room) If you accidentally quenched the magnet the liquid helium would flash vaporize and displace all the oxygen immediately. You had about 20 seconds at most after a quench to get to the wall and pull the handle or you would go unconscious and die.

Good question! It's called multilayer safety. Basically You absolutely have a sensor to detect dangerous events that need reacting to. But...where do you put the sensor? And how sensitive is the sensor? Too sensitive and it goes off just from normal events. Not sensitive enough and it's useless. So you have a middle ground. But that middle ground, plus where you place the sensor may mean that it doesn't detect things as fast as you do. Or maybe it does. Regardless, Having the human being in danger primed to run away from the danger towards a a lever is a good idea. And so the system may already be activating, But on the chance it isn't, the human is a backup safety device. And if the system IS working, the human is running away properly. 2 layers of safety in one device!@@shanent5793

Big magnets near transformers will also cause the inductance of the windings to decrease, which can cause the current in the primary winding to increase, which might cause a switch mode power supply's overload protection to trigger, a fuse to blow, or something to burn out. My guess is that in the video, some kind of overload protection triggered before any permanent damage was caused.

Left hand rule is always confusing, but somehow, seeing that Windows 7 screen move up and down just made it click. I've got a fun idea: can you keep the electron beam stable with two opposing magnets on either side?

@legendarygigolo823

No, because the beam travels left to right and down the monitor, exactly like you read the words on a page. Because of that movement, one magnet will always have more effect over the other on the electron beam since it's closer and the image will still be distorted.

Something about the plasma globe + 46" TV lamps scene is absolute art. What a lovely angle and color palette.

And one camera even turned off at some point. I think they use a magnetic sensor to sense when the flip-out monitor on the camera is closed - with a little magnet in the monitor frame. The big magnet made the camera think the monitor was closed which is a sign to turn off :)

This video reminds me of a story that my father told me: His TV wasn't working properly so they had a technician look at it, but he saw no problems. So after he left they set it up again and the issue happened again. The technician came back and it worked fine. This time they set up the TV with it switched on, and when they placed a magnetic sculpture on top the issue came back!

I absolutely love your videos. Each and everyone of them is a pleasure to watch.

the screen distortion looked so cool

As a former physics student I have never watched a better demonstration of the left hand rule. And when I was a student CRTs where basically the only display technology. Guess even then education was starved of resources and nobody wanted to risk breaking a TV.

11:00 i like how you used a bike tire lever to take apart some of the monitor. XD

Since moving magnetic fields induce current, I wonder if you could move a large magnet near either monitor quickly enough to cause permanent damage (in a safe manner)

Holy COW! I had no idea your big magnet would screw with a CRT so badly and even from so far away! Yeah, I've messed up CRTs with even tiny magnets as a kid, and what sucked is that some were so old that they didn't have a degausser, so like... on my parents' TV they'd just get mad for a bit and then we'd have to wait months for the discoloration to finally be gone. What was fun later is to mess with a CRT that has a degausser and then you can just degauss it once or twice and it's back to normal.

Was always a problem doing magnet therapy with clients watching TV . Even the large screen TV had a CRT in the bottom focused with a Firenzel lenze on the screen.

When I complained about the necessity to follow the conventional current direction when applying Flemming's left hand rule, my teacher told me just to use my right hand instead as long as I remembered to switch hands when appying it to generators. Somehow you made me miss him.

I liked the monitors with manual degausing. I didn't know what it did at the time, but it felt cool to me and I always felt like it made everything look better. Just like the turbo button on my PC.

I never knew that hand trick, thanks for showing us thanks

That LCD panel from 2009 uses a CCFL tube CCFL tubes do use more power than LEDs. CCFL require high voltage to use as seen on the circuit. LEDs just need 12,24, 36 or 48 volts, larger the monitor the more voltage the LED backlight needs.

There's an old saying "All roads lead to Rome", now i wonder if "All compasses point to Brainiac" Maybe a suggestion, take your magnet somewhere, then use a standard compass and maybe mobile phone compass app to see how far away you need to be to not have then influenced by the magnet. ;)
