Hi guys, I am having quite the struggle finding a good resource to explain the difference between the magnetic force associated with moving charged particles (Lorentz Force) and just the regular force exerted by a magnetic field on a magnet or ferromagnetic material. I am trying to apply this to the solenoid valve, which is essentially just an electromagnet that creates a magnetic field which moves a plunger. In this video: the gentleman says at around the 0:08 mark that the magnetic field pulls the plunger, I am curious as to what force is pulling this plunger. It is not the Lorentz force because there are no charged particles moving in the plunger, so what other type of magnetic force is at play here? Any sort of clarification or resources would be very appreciated, Thanks.
