Part A 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 9.70 MHz . At this field strength, the Hall voltage on the probe is 0.546 mV when the current through the probe is 0.143 mA . Later, when an unknown magnetic field is measured, the Hall voltage at the same current is 1.740 mV . What is the strength of this magnetic field? Express your answer with the appropriate units. HA ?
