It is time to find out, how magnet proof an SD card marked 'magnet proof' really is.

I will thoroughly test the card and its data near some 1 tesla neodymium magnets and even go as far as to cook it on an induction cooker. A 2000W ~20 kHz AC electromagnet build for inducing serious eddy currents.

Will I be able to delete or change some data? Even when tested down to the last bit in every byte? I was surprised by the outcome...

SD Card vs. Monster Magnet and Induction Cooker (2000W AC electromagnet)

Thanks to Brilliant for supporting my channel with the sponsorship. Use this link https://www.brilliant.org/Brainiac75 for 20% off on the premium subscription and help me out at the same time. Are SD cards really magnet proof? Even when thoroughly tested near some of the strongest permanent magnets available? And what about the AC electromagnet in an induction cooker? Will that affect the data on an SD card? Let us find out!

Keep up the great work! I thought for sure the cooker would have done something to it.

Thank you very much :) Much more to come. I did not expect the card to withstand being between the pot and the induction cooker for an extended time... But I have learned a new term from this: Skin depth. If the thickness of a material (everything in an SD card is thin...) is below the skin depth for the material at the frequency used by the induction cooker, then the induction cooker will not have much effect on the material.
