Are there any theories concerning the possibility of magnet lasers? A magnet laser would be similar to an optical laser, but instead of light it sends a concentrated beam of magnetic force. Is this even theoretically possible?

3$\begingroup$ By "concentrated beam of magnetic force," do you mean oscillations in the magnetic field which, in a certain range of wavelengths, are more commonly referred to as "light?" $\endgroup$– SandejoCommented Feb 23, 2023 at 7:22

The stimulated emission of light is the crucial quantum process necessary for the operation of a laser.
To get lasing action one has to create an electromagnetic field.
Accelerating electric dipoles can radiate, as seen in the chosen answer here.. The mathematics will be analogous for accelerating magnetic dipoles, so accelerating a magnet will generate radiation, and elaborate technology may allow having a coherent enough radiation to create a laser. It would be a very inefficient way both in difficulty in the experiment and in money spent. There are much easier ways of getting coherent electromagnetic waves.
