Re: shielding from EMP?

Body

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.

 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.

 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?
