Hi,
Is it Convenient to ask about this Propulsion idea?
Please refer to this picture:

Propulsion.png

Please consider Both Metal plates and Both Solenoids are attached together, so there
is no possible movement between them.

They can move only as a whole/attached together.

The magnetic field from Current carrying Solenoids is Pulsating ,
but The North poles of Both Solenoids are always Pointing toward Metal plates
(Please consider them to be perfect conductor).
In this case the Pulsating magnetic field/EM field will be the "Propellant".
Will there be in some direction (On the attached picture) net thrust/motion ?
Thank you.

This is very much like Photon rocket:
Photon rocket - Wikipedia
but instead photons as propellant
the propellant is Magnetic field.
Thank you

what's the wavelength of the emitted photons?

Lets consider very hugh frequency.

Again, this is like trying to pick your selfup by your boot laces. It violates conservation of momentum to produce a uni-directional force from this setup.

Microwaves or X-rays?   From the drawing to me it looks like the best you are going to get is microwaves.

photon momentum is inversely proportional to wavelength.

Your TWR is going to be so tiny it will take forever to get anywhere.   Even Gamma rays would be tough.  You aren't getting gamma rays out of a solenoid.

any photon drive needs to focus on TWR and energy efficiency.  You need to convert energy into photons with very high efficiency and with very low mass.

Probably get more thrust from drag on the solar wind.   Why not use those magnetic fields to sail the solar wind.

I think he said he's producing photons.    That makes it a photon drive with a novel implementation, not picking yourself up by your bootlaces

He said magnetic field instead of photons, so it's not a photon drive.
