Nearly a year ago, I hit upon an idea with which I try to make an analogy between the Coriolis force (F=2mv×Ω,) and the Lorentz force (F=qv×B) due to an induced magnetic field. I see that these forces are generally incapable of doing work since they are perpendicular to the curved path of the particle, and they are both proportional to the velocity of the particle. The only difference is that the Coriolis force acts on any particle regardless of whether it is charged or neutral, whereas the Lorentz force is exerted on charged particles.
I try to design a thought experiment in which the Coriolis force is entirely eliminated by a Lorentz force both acting on a charged particle. Can someone tell me if this idea is plausible or if there are some references regarding this matter?
It sounds totally plausible to me, and can probably be demonstrated for slow charged particles,. However, the Coriolis force is a fictitious force that operates in a rotating reference frame to explain the motion of particles traveling without the Coriolis force in a non-rotating frame, and the fictitious Centrifugal force must also be included to describe the motion correctly. You may be able to do an experiment near the centre of a rotating reference frame where the Centrifugal force is small where the Coriolis force can be made to balance the Lorenz force over a small distance if the velocity is chosen carefully to get the Coriolis force to dominate the Centrifugal force over a reasonable distance. I am interested to see if this has been done, and look forward to other answers.
Doing things accurately, for large rotation rates, I suspect relativity might need to be included to get the correct magnetic field in a rotating reference frame.
Dr. Javanshiry, The commonality between the Coriolis force and the F = qvxB force is discussed in sections V and VI of this article,
Article Aether Friction in the Planetary Orbits
This mainly discusses their common physical origins.
As for setting up a rotating system whereby a Coriolis force would cancel the magnetic force, it would be a matter of getting the correct geometry. I'm not sure though that this would be possible. The Coriolis force is a transverse force in a rotating system, whereas when the magnetic force is causing a charged particle to undergo circular motion, it is a radial force. I'm not sure how we could set up a rotation that would cancel this radial force.
But it's an interesting question.
