I brought this up years ago with some retired electronic engineering friend's.
One dI'd mention occupied iron and another the mumetel which I played with.
I bought also at the time of sheet green in colour for showing magnetic fields.
I remember playing with it and testing out each value bench guessing lol
The occupied iron did work fairly well maybe enough?
I asked the group at the time as my shop was the place of drinking coffee and teas,
about preparing. One gentleman said keep all components fresh that have never been exposed to any value under a sheet of tin and if you can lead. Then should there be an incident
you are ok . It was about 2005 lol

By the way it doesn't seem to be possible to shield the motional electric field. This makes even toroidal wound transformers radiate. The field from Alexey Chekurkov's levitating device destroys electronics. The Searl effect generator also interacts with electrical systems. Both of these devices having mechanical rotating charges make them generate motional electric fields.

Ole

Hi Mick,

Iron is a good magnetic shield. For fast rise time a good electrical conductor like copper or silver will do too. The magnetic field induces eddy currents in the electrical conductor which mirrors the magnetic field and thus cancels it on the inside or outside of the shield. Iron with its greater electrical resistance dissipates more of the magnetic field as heat.

Regards
Ole

As we know the E field can be shielded by a Faraday cage while the B
field is another consideration.

What is the best way to shield electronics from the fast risetime HV B
field,  what type of cocoon would be best?
