now I see, thanks much... next, can you teach me how to post equations like you do?

The hall effect is similar to the relevant equation I posted since the hall effect assumed that the moving charges are electrons. Therefore, the drift velocity was talking to velocity of the density of moving electrons. relevant equations: B=F/qv, looking for F, we have F=qvB Hall effect: F =...

1.Suppose that a blood vessel is 2.5 mm in diameter, the magnetic field is 0.08 T, and the electromagnetic force is 0.10 mV. What is the velocity flow of the blood? Assume that blood carries charged ions. Homework Equations B=F/qvattempt looking for v isn't possible since I have no idea how to...
