Thanks Tom, very helpful. Is there any difference between a Hall effect sensor (https://www.ti.com/lit/ds/symlink/drv5056.pdf?ts=1676951464566&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDRV5056) and these handheld meters (...

Right now, I don't have the drive circuitry. Working through everything in parallel. I asked about measurement because I'm trying to see what tools I need to buy for building and validation.

Interesting idea. How do I use an oscilloscope to measure magnetic fields?

https://en.wikipedia.org/wiki/Transcranial_magnetic_stimulation I'm not planning on building one that can achieve therapeutic levels, just using this as inspiration to build a small wave generator.

Thanks Berkeman! I actually don't have a great background here. Many many years ago, I did study one year of electrical engineering before switching to mechanical. I'm trying to hack together my own TMS machine mostly for fun and as a way to get back into things (inspired by success of...

Hi all, Looking to measure some magnetic waves being generated at an electric coil. Freq is between 0-20kHz and magnitude is pretty small <1T. Any have suggestions for the best tool to measure and log data of this magnetic waveform? Googling around, I found meters like this: [Possible spam...
