PHYSICS 1C Lecture 3: [Wk1.Wed] Hall Effect and Biot-Savart Law

In a hall effect sensor the__________varies withthe___________.

a) magnetic flux/Hall voltage

b) magnetic flux/applied current

c) Hall voltage/magnetic flux

The Hall coefficient of silver is R(small h) = 8.4*10^-10 m^3/C. Design a Hall Probe that a current of 5.0 A would produce 0.1 micro Volt in a 1 tesla magnetic field?

The conduction electron density in germanium (a semiconductor) is2.01x1024 rm m^-3. The Hall effect is observed in germanium using a0.150 mm thick bar in a magnetic field of 1.15 T.

Find the current required in the bar in order to produce a Hallpotential difference of 2.0 mV.
