Magnetized Biochar

Hey folks

I recently heard this mentioned as being beneficial in raising the paramagnetism of soil by Mr.Powers.  As I did not know what it is I searched and came up with many studies mentioning it and did not see any basic articles describing it, how it is different from regular biochar or simple ‘how-to’ guides.  In the studies there is some mention of adding minerals like iron or magnetite to magnetize it, however their language is obscure to me.

Has anyone a link to a simple guide on understanding magnetized biochar?  Also mentioned as Activated Magnetized Biochar (AMB).

Cheers 🌞

Interesting topic.  This article talks about using magnetic biochar to possibly prevent heavy metals from contamination.

It may be related to electrical conductivity. I have read a few sources that described the electrical conductivity as a beneficial way of distributing nutrients via the mycelium in the soil, and retaining the minerals through some very wet periods that would normally leach out minerals. We get very drizzly winters here in PNW, that leach out calcium, zinc and boron.
