How Do Electromagnetic Fields Affect Liquid Movement?

Click For Summary
SUMMARY

Electromagnetic pumping is an effective non-invasive technique for moving liquids, particularly in scenarios where traditional pumps are impractical, such as with liquid metals. This method utilizes simultaneous application of electric and magnetic fields to generate movement. The discussion highlights the need for clarity on the force acting on ions within the liquid, specifically questioning the relevance of the formula F = IL + B and the meaning of the variable L. Understanding these principles is essential for effectively applying electromagnetic pumping techniques.

"Electromagnetic pumping is a non-invasive method of moving liquid used in situations where the moving parts of traditional pump are not practical. Pumping liquid metal is an example. Electromagnetic pumping involves applying an electric field and a magnetic field at the same time. Consider a pipe oriented perpendicular to the screen, a magnetic field applied from left to right, and an electric field directed upward. Determine the direction of the force on an ion in the liquid. Does the direction of the force depend on the charge of the particle?"

Don't even know where to start with this one. Looked and looked for appropriate formulae but the only one I could find was F = IL + B. Is this right? If so, what does the L stand for?

Thanks
