Hey there,

[size=0px]I think the photosensitive material is too resistant.[/size]
[size=0px]An inert gas arc discharge should be initiated with a laser in a vacuum tube,[/size]
[size=0px]And guide the arc to move (I don't know if it can).[/size]

You're right.
Oxides based LDR are resistive, but there are other ways (nanomaterials).
Plasma discharges are indeed another way to implement this, think about detonation front propagation (laminar flow) also a way to do it, cold plasma another one, there are indeed many way to get this done, but the important part in this setup is the fact that there would not be a reacttive force against the movement of the laser(or any other light source, or if a slit is used, against it ), think about a circular setup like in a generator, the only reactive force would act against the conductive region itself but not against the slit or laser beam. the perfect lenz free generator ? Could be.
And yes, one could weaponize this also, think about having a circular(round) conductive region colapsing or expanding really really fast. the reactive force would act on the ldr plate itself destroing it(imploding or exploding it), yes there are many more implications to this.

when a conductor with proton conductivity moves in a magnetic field,
Will the force opposing its movement be directed in the same direction as in an ordinary copper wire ?  I mean the force proportional to the current in the conductor (load current)

This unfortunately won't work. It is necessary to move the charges themselves in a magnetic field, and not a virtual conductor. With a high probability, there will not even be any EMF at the conclusions of the photoresistor.

Hello @kolbacict,
That would be right , but,

When the conductive region moves while the initial magnetic field remains constant, the motion of the conductive region itself does not directly induce an electric current. However, if the moving conductive region intersects magnetic field lines, it can experience a change in the magnetic flux, which could potentially induce an electric current.


According to Faraday's law of electromagnetic induction, a change in the magnetic flux through a conductor induces an electromotive force (EMF) in that conductor. This induced EMF can, in turn, cause a current to flow if there is a complete conducting path.


In the scenario described, where the conductive region moves but the magnetic field remains constant, the relative motion between the conductive region and the magnetic field can result in a change in the magnetic flux through the region. This change in magnetic flux can induce an EMF in the conductive region.


If the conductive region is part of a closed circuit, such as a loop of wire, the induced EMF can drive a current to flow through the circuit. The magnitude and direction of the induced current will depend on factors such as the speed of the motion, the angle between the motion and the magnetic field, and the size and shape of the conductive region.


It's important to note that while the motion of the conductive region can induce an EMF and potentially a current, this process requires a change in magnetic flux. If the magnetic field remains constant and there is no change in the magnetic flux through the moving conductive region, there would be no induced current.

An experiment could confirm the assumption.
It needs to make a large homemade photoresistor.
I don't know yet how...
