Hall effect Definition and 116 Threads

Me and a friend are working on a research project that involves four-point electrical measurements. (Van der pauw) To do a hall effect measurement, the sample and probes have to have a strong magnetic field pass through. So we want some design ideas on constructing the mount that will have to be...

Homework Statement Show that the Hall voltage reverses sign if either the current or magnetic field direction is reversed, but the voltage offset reverses sign only if the current direction is reversed. Use the information to confirm the validity of equation see eq1 image Homework...

Homework Statement A thin metal film of length 1.00 cm, width of 0.250 cm, and thickness of 29.0 micrometers is used to measure the Hall effect. A current of 2.60 A is maintained along the length of the sample. The Hall voltage of 16.0 microVolts is detected across its width, when a magnetic...

Homework Statement metal strip 6.66 cm long, 1.11 cm wide, and 0.837 mm thick moves with constant velocity through a uniform magnetic field B = 1.55 mT directed perpendicular to the strip, as shown in Fig. 28-37. A potential difference of 2.99 µV is measured between points x and y across...

im thinking of the classic airplane problem. the one where the flying airplane develops a voltage across its wingspan. now this was posed to me as a motional emf problem and i bought it then but simultaneously thought that it seemed like a hall effect problem. so two questions now that i think...

Hey there. Trying to figure out how to find a hall voltage across a ribbon. I'm given J, B, and some other factor: R-sub-h OHM*meter/tesla. (no clue what this is... :redface: )I'm also told to assume the charge carriers are e-'s. I understand that the hall effect is used to determine which...

Using the leybold hall effect apparatus for silver http://www.leybold-didactic.com/phk/produkte.asp product ID: 58681. Dimensions l = 0.064m (distance between contact), breadth 0.02m, and thickness 5E-5 m micrometers. Resistivity of silver \rho = 1.89x10^{-8} \Omega m Resistance R =...

hi i am in a bit of a pickle and could do with some advice. i have a built, working, hall effect thruster (http://en.wikipedia.org/wiki/Hall_effect_thruster) but can't figure out how to measure the thrust it produces. any ideas? thanks stuart

As I understand it, a current flowing through a conducting strip in a magnetic field perpendicular to the current will drift to the side creating an electric field that corrects the currents motion and creates a potential difference across the conductor. Why then does a current carrying wire in...

I'm perplexed by semiclassical treatment of Hall effect. I'm referring to Aschroft Mermin text. At page 233 is my doubt: why is it necessary the introduction of w drift velocity vector and why does it take that form? :rolleyes:

If I move a strip of copper mechanically with my hand through a uniform magnetic field will their be a drift velocity? And if so will the drift velocity be in the same direction as the moving copper strip? What would the magnitude of the drift velocity be if this happens? Can you have a drift...

OK, we had Hall-effect equivalent for photons. And now there is Hall effect for phonons! http://physicsweb.org/articles/news/9/10/5/1 Zz.

Hi there, I am currently learning about the quantum hall effect and am a bit confused about the edge states picture and how this fits in with the rest of the theory. In most books/review texts the theory is dicussed from the point of view of an infinite 2D system the magneteic field collapses...

Hall Effect! Relocated Hey guys, I'm having a little confusion. Have spent too much time in trying to work through this. . . In performing the Hall Effect experiment, I took data of the Hall voltage versus Temperature. I performed this three times for different fixed B, magnetic fields. The...

hello, here is my second message.(and my English is still very bad) I don't understand these 3 little experiments(we need Helmholtz coils and a Hall Effect probe) I know I have to draw a graph for each situation but I can't interpret the difference between the theory and the experiment...
