/diy/ - Do It Yourself

There's more to this than just meissner effect. If anything, the videos do it a disservice (just look at Dave from EEVblog's imbecilic take) as the isolated samples are very likely not pure enough and sputtering it onto copper then making the copper wiggle about may not have been the best idea without also showing the copper by itself to have something to compare to.
There are two ways to approach it, one is in simulation as it was done in this paper >>2659034 and the other is to take actual measurements for magnetic fields and resistance.
>>2660139 diamagnets are polarity independent. If anything that's their defining feature.
