Amazing Video.. What's about shielding Neodimum Magnetic field from one to another Magnetic field ?

[@philipdonovan5127]

Thank you, very insightful and helpful. I"m building a guitar tube amp from a donor cabinet where the 2 power tubes are forced to be close to the speaker magnet. Its been shown that depending on the situation, the proximity can deflect the electrons in the tube causing distortion in the signal and effect the output as well. Should this end up being an issue, I was on the hunt for a solution to keep the magnetic profile of the speaker from effecting the performance of the 2 power tubes. I would expect this frequency of the speaker magnet to anywhere from the steady magnet field throughout the audio frequency range. Its hard to tell right now but, it might be wise to at least anticipate a potential issue with this and have some approaches to experiment with. Thank you! Great video.

Hi, I've seen that MuMetal material is very popular in shielding. What do suggest for shielding transformer / substation? Are they at 50-60 Hz? Thnx 👍

[@Conservative4]

Hi! Thanks for the video, I’ve been curious about shielding from EMP bursts, such as a solar flare or nuclear weapon. Most vehicles are made from a light stainless steel and and I find little data as to whether a vehicle would stand up to an EMP if we had a “Carrington Event”.

[@LearnEMC]

Solar flares and the E3 component of nuclear EMP are very low-frequency events that are unlikely to affect vehicles. These are more of a threat to power and communication grids with very long wires. The E1 and E2 components of a nuclear EMP event could affect or disable vehicles, but at these frequencies, any shielding provided by the vehicle body would be more related to the conductivity rather than the magnetic properties.

[@Conservative4]

@@LearnEMC Thanks! I really ought to learn a lot more about this.

[@sahalsafwan1752]

[@acacianorison]

Thank you so much. What is the commercial stainless steel tile use in shielding against low frequency as low as 15Hz. Can mumetal be used?

[@roshanbalachandar4315]

I heard the usage of " shunting " a lot . But I was expecting the shield would be producing " Eddy currents" that try to cancel or attenuate the flux being produced by pri coil

[@LearnEMC]

That happens at higher frequencies (kHz and higher). See the video "High-Frequency Magnetic Field Shielding Demonstration." At very low frequencies, the conductive loss in the material prevents the eddy currents from being strong enough to significantly attenuate the magnetic field.

[@NeuralCatch]

Super helpful video. Thanks for making it.

[@Swayzeo]

If you would have grounded all the metal plates, would you get more shielding?🤔

Is there anyway to shield against magnetic shielding in a home?

[@imacenurface]

There was a huge change in the copper... look at the screen on the gauge thing you have . It dimmed the light on the instrument screen

[@ollie-d]

That was an artifact from the camera's auto focus. The actual amplitude as measured by the oscilloscope is not affected. The illumination of the screen wouldn't be affected either way as you could see with the shielding steel.

Is there a direct correlation between absorbing the magnetic field and heat pickup ? Lets say you effectively absorb 100% of the field, how dangerous is that with heat building up (heating stove ?)

[@cintraan001]

could you show how neg charged magnets affect magnetic fields. I heard of products people who are targeted by scalar harmonics will use EMF harmonizers, Quwave Defender, Rezotone 5G shield, Aulterra 5G shield, 5G bioshield, taking Zeolite which has neg ions, Neg Ion Generators, drinking ionized water...any of these things work? Some will paint their home with RF Shielding Paint (charcoal and graphite) or go with Iron Ball Paint to get away from EMF/RF/ELF. I think Smart meter puts milliwave and scalar tech throughout the home which communicates with smart appliances, computers, wifi routers. how can someone have a zero faraday home shielded from ELF/Scalar/Harmonics/RF/EMF? I was thinking one can also run EMT/Flex electrical wiring and pull wires out of a room or two until you sell. Now, even water meters have Smart Meters which pulse RF/EMF throughout your plumbing system. So you have plumbing and electrical being used to radiate RF waves. Why? thanks for the video.

[@DreamhouseVideography]

Interesting. Good job explaining. Can you tell me... will putting a sheet of thin copper underneath my laptop block emf (and make it safer to use when it sits just above my lap)? Thank you.

[@DreamhouseVideography]

[@yt4krist0f]

Would it be any difference if the shielding was a) built as a box/cage around the coil and/or b) if the shield itself was grounded?

[@LearnEMC]

The magnetic materials would work better around the whole coil, the non-magnetic materials still wouldn't work. Grounding makes no difference.

[@hemiolabooks450]

Thankyou, just what I needed to see. I'm currently trying to stop stray flux from my amplifier transformer interacting with the Tape head of my cassette deck which sits below it. Does the thickness of the mu metal have a bearing on its effectiveness? From what I've read on ebay they say not....but I would prefer your opinion!

[@LearnEMC]

The thickness affects both the reluctance and the saturation flux. Nevertheless, your application probably doesn't require a very thick sheet.

[@hemiolabooks450]

Thanks. I just checked the Mu Shield company's Facebook page and their last post was about a turntable similar issue finally enough. Watching that half success makes me wonder if I need something pretty thick. The flux field from my amp seems quite large - I have to lift it above my deck by about 15" to eliminate mutual induction. In your video, if the sheet had extended well beyond the diameter of the coils would the attenuation have been greater?

[@LearnEMC]

@@hemiolabooks450 Extending the shield material farther out from the loop boundary would have provided some improvement. The lower the reluctance of the shield path relative to the air path, the better it works. I can't comment on your amplifier interference problem, I don't have enough information. Nevertheless, you can experiment until you find something that works.

[@LearnEMC]

The last material was a sample of a mumetal marketed and sold by MuShield . Mumetals have very high relative permeabilities at low frequencies. You can find a very good explanation chaotic magnetic fields at physics.aps.org/story/v24/st24.

"Stay Out of Fear & Be Proactive: You have to shield your mind from fear, remain resolute, positive, and strong. Why? Because you can actually improve your vibration through positive thinking pattern, cheerfulness, forgiveness, and with an improved focus toward mental, emotional, and physical health."

[@MasterFeiFongWong]

"Earthing: Earthing is often ignored but it can be powerful when you’re looking to protect yourself from 5G radiation and EMFs. In other words, “be an extension of the earth, not separate from it.”Make a decision to spend at least 3 hours in a nearby forest every other week. Why? Because trees absorb our negative energies, connects us to nature, improve our immune systems, and nourish our hearts and souls. Interestingly, when you hug a tree and walk barefoot in the foods, gently matching dry leaves, you’re in for a heavy boost in your health, mind, attitude, thoughts, and intentions, as quite possibly, your current life-trajectory. It’s good to connect with the earth in such a way, as it nourishes our meridians and electromagnetic systems, which is powerful enough to protect and empower us. If you seem to not have as much time to spend in nature, we do carry earthing products here at Purahome. The concept of Earthing is this… The research indicates that Earthing transfers negatively charged free electrons into the body that are present in a virtually limitless and continuously renewed supply on the surface of the Earth. The existence of this unseen electron “reservoir” has been established by science. Maintaining contact with the ground allows your body to naturally receive and become charged with these electrons. When thus “grounded,” any electron deficiencies and free radical excesses in the body are corrected. A natural electrical state is restored. Electrons are the “object of affection,” so to speak, of positively charged free radicals, the biochemical agents that cause oxidation in the body. Electrons are the source of antioxidant power. This influx of electrons from the ground serves to potently neutralize or quench free radicals that would otherwise steal electrons from healthy tissue, activity resulting in tissue damage and chronic inflammation that is at the core of many common and serious diseases."

There are no eddy currents at 0 Hz. And at frequencies on the order of 100 Hz and lower, they are attenuated by the resistance of the metal, so they don't provide enough magnetic flux to oppose the incident flux.
