SOLVED: A Hall-effect probe to measure magnetic field strengths needs tobe calibrated in a known magnetic field. Although it is not easy todo, magnetic fields can be precisely measured by measuring thecyclotron frequency of protons. A testing laboratory adjusts amagnetic field until the proton's cyclotron frequency is 10.2 MHz .At this field strength, the Hall voltage on the probe is 0.549 mVwhen the current through the probe is 0.146 mA . Later, when anunknown magnetic field is measured, the Ha
