How Do Electromagnetic Fields Affect Liquid Movement?

AI Thread Summary
Electromagnetic pumping is an effective non-invasive technique for moving liquids, particularly useful for liquid metals where traditional pumps are impractical. This method utilizes simultaneous electric and magnetic fields to create movement, with specific configurations affecting the direction of force on ions within the liquid. The discussion raises questions about the relevant formulas, particularly F = IL + B, and seeks clarification on the meaning of 'L' in this context. Participants express confusion over the application of these concepts and the underlying physics. Understanding the interaction between electromagnetic fields and liquid movement is crucial for advancements in this technology.

"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

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
