I Review A Hall-effect probe to measure magnetic field strengths needs to be calibrated in a known magnetic field. Although it is not easy to do, magnetic fields can be precisely measured by measuring the cyclotron frequency of protons. A testing laboratory adjusts a magnetic field until the proton's cyclotron frequency is 9.80 MHz . At this field strength, the Hall voltage on the probe is 0.547 mV when the current through the probe is 0.141 mA . Later, when...

A Hall probe is calibrated using a magnetic field B that causes protons to have a cyclotron frequency fcyc = 9.7 MHz. At this field strength the Hall voltage is AVH= 0.570 mV when the current through the probe is / = 0.17 mA. The probe is then placed in another magnetic field B and the Hall voltage at the same current is measured to be AVH = 1.750 mV. What is the strength of the unknown magnetic field, B?...
