I am studying the Hall effect sensors in the book and found a question:
Considering a large pipe, with a diameter of 1.2 m, is carrying water, at the speed of 8 m/s. The pipe is subjected to the action of the Earth magnetic field, perpendicular to the pipe.
What is the magnitude of the Hall voltage induced on a Hall sensor placed on the surface of the pipe?
The first formula that comes to mind is V = R*i*B*sen(a)/thickness ... but I don't think I have enough data.
Then I tried Lorentz force: F = qvBsen(a)* --> E = vB = 480uV
Is this correct?
