Errata: (omitted) The frequency of the mag field oscillation is tuned to the coil's resonant frequency. Tuning provides more efficient power transfer. 👉 Gadgets https://www.etsy.com/ca/shop/AvEwerkz

Back to revisit from 5 years ago. Special occasion. Field strength of an electromagnet (or any magnet is on a logarithmic scale) The field flux decrease by a factor of 4 at half the original distance. They are simple, and have been used on inductance stove tops for a long time. However, you must use a ferrous cooking pots. As an electric field, has a very minor effect on many metals. The stove top remains cool to the touch, only heating the contents.
Ooo. Wiggly bits. Jfm. Like my girlfriend and her left hand sister.
I really love your content. I couldn't find your channel for a while. My life was incomplete😒 There simply aren't enough Xanax in the world.
damn I dont want to know the troble, this workbench has seen😅
That's JFM if'n I ever did see it
Uncle Bumblefuck just explained this to me 3 separate times in 15+ minutes of watchin' and re-watchin' and I still don't get it.
TIL I am dumb as a bag of hammers.
what you don't mention is that the wireless charger sends out small pulses like you see in the LED until a device is put on top to receive the pulse, after the device receives the pulse, it sends a acknowledge pulse back which turns on the constant high power oscillation on to to charge the device
What I don't understand is what is happening on an electron level. Is the receiver coil emitting its own electrons that are stored? Could we theoretically wear a receiver coil out as it runs low on electrons?
Had to subscribe if only for the terminology 🙂
So if i stick a small coil with a magnet in my outerbox case it should amplify the qi charge and charge my phone faster?
Simple transformer. Must the frequency be precise for the phone to recognize it? Is it a sine wave? The scope is right there and we didn't get to see the actual waveform?
Thank you
Late to the party, and you have probably long answered this question but is this how brushless motors work? Seems to me like if you can get enough current over small enough of a inductor would be a better way of running the commutator
So if I put coil of wire around my wing dang doodle and a magnet on my wrist I could power my house
