The magnetic devices DO work.
But they do not remove scale and so do not soften water.
They should be called water conditioners.
They only work to some extent and exactly to what extent depends on the application and exactly how they are fitted.
The electronic ones should also work but the magnetic field they produce is so weak compared with the permanent magnet ones that I dont see how they can have any significant effect.
The electrolytic ones also work to some extent but are rarely seen.
