magnetic field of the human brain

[ElectroMichel]

Does the human brain produce AC or DC magnetic fields?

I would presume that since the connection are short pulses they would be seen as AC.

While the brain can be manipulated by magnetic fields, almost all measurements of brainwave activity are electrical.

Static electric charge can only generate an electric field, but moving charges (as one has in brain activity) create magnetic fields. Both are very weak.

In the form of AC or DC magnetic fields?

 

[MagBen]

Billions of nerve impulses in the brain create complicated changing human magnetic fields. These changing fields induce changing electric fields. These two fields are correlated to carry messages.

It's apparently been done, at least once,
