RADIATORS ARE MAGNETS? Surprising Effect and Direction of the Earth's Magnetic Field

Are the radiators in our homes affected by the Earth's magnetic field? Radiators are typically made of steel or even cast iron, that can get magnetized in a magnetic field due to ferromagnetism.
And does it depend on where on our planet you live? The direction of the geomagnetism varies quite a lot from fully horizontal to fully vertical...
Let's find out how and how much the geomagnetism magnetizes radiators!

Thanks to RadiaCode for sponsoring this video! Use promo code "Brainiac75" for 10% discount: 103.radiacode.com/ LEDs have become standard lights on modern cars. They emit a lot of light and use fewer watts than the old-school halogen lamps. But are car headlamps getting too bright? In this video, I test three types: halogen, LED and a rare, laser-based LEP. I measure their spectrum for color re...

Thanks to RadiaCode for sponsoring this video! Use my promo code "Brainiac75" for 10% discount: 103.radiacode.com/ Microwave ovens have a magnetron that produces the microwave radiation. The magnetron needs a magnetic field from its built-in magnets to work. So what will happen if I place a very strong magnet on top of a microwave oven? Will the magnetron stop working, get stronger or just work...

Can a Class 1 laser remove hair? I was faced with this question when I found an old hair removal laser in a thrift shop. It is labeled as class 1 - the safest of all laser classes. Being sceptical, I bought the laser and will in this video test its wavelength on a spectrometer and its power on a laser power meter. Can you guess how strong it is? And is it a safe class 1?

I want to test my expensive set of rare earth elements. Are they the real deal or have I been fooled? But I want to test the metals without breaking the sealed glass/argon tubes they are stored in for protection. What to do? Time to bring out my strongest magnet and test the rare-earth metals in part 7 of my classic series: Exotic Elements vs. Magnet! Is the rare-earth set genuine? Let's find o...

Time to power up my most expensive lamp. Due to a wrong delivery, I have three power options to choose between. In this video, I test and compare how well they light up the low-pressure sodium-vapor Philips SOX 135W lamp. Which is better? The ballasts BSX 91, BSX 135 or the leak transformer L4135? One of them is not really meant for a 135W lamp, but it is the most modern and perhaps the best op...

Why does a flicker-flame lamp flicker? And why is the beautiful gas discharge not taking the shortcut between the closely spaced electrodes? In an attempt to figure out how such a specialized light bulb works, I will test my only flicker-flame lamp. One that seems faulty, but still turns out to be stunning when slowed way down. A marvelous demonstration of Paschen's Law. Let's take a closer loo...

Having efficient light bulbs is great. It saves energy which gives you lower electricity bills and lower impact on the environment. So why have we stopped using the very energy-efficient low-pressure sodium vapor lamps? In this video, I take a closer look at this vintage technology and compare it to modern, state-of-the-art LEDs. How do they compare in luminous efficacy and color rendering inde...

What happens if you wear a finger ring while touching a plasma globe? What if you jump while touching the plasma globe? Why are the filaments attracted to us? Is grounding - electrical earthing - needed to attract the filaments of the plasma ball? So many questions to answer but I will give it a try in this video. Luckily, plasma balls are relatively safe sources for high-voltage experiments :)...

Handheld, yellow lasers do not exist. That is my experience after I last year tried three that were advertised to emit some shade of yellow. None of them looked yellow to me... In this video, I give it another try. Can I fill the yellow gap between red and green with a new laser that should emit a wavelength right between the ones I have tested to be closest to yellow? Is it true yellow? How po...

My yellow-green laser module is not even close to performing as advertised. Perhaps because the power supply is less powerful than advertised too? In this video, I max test the power supply and see if it matters. I also build a pulse-width modulator using an Arduino Uno in an attempt to adjust the laser's power output. Will I succeed?

Ferrofluid is amazing. I wish everyone could experience it in real life, but it is expensive. Perhaps there is a cheaper alternative in your local store: Magnetic paint! In this video, I test the weird paint and compare it to ferrofluid and my own creation: ferripaste. How well does magnetic paint work in comparison? What are the fluids' strengths and weaknesses? Is one of the disadvantages of ...

I like fiber optic lamps but their brightness always disappoints me. They are too dim to really impress me. No matter if it is an old halogen or new LED type. Time to upgrade my two fiber lamps! Make them brighter - much brighter. Will I succeed or is there a limit I overlooked?
