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...

3. A Hall effect probe to measure magnetic field strengths needs to be calibrated in aknown magnetic field. Magnetic fields can be very precisely measured by measuring thecyclotron frequency of protons. A testing laboratory adjusts the magnetic field until theproton’s cyclotron frequency is 10.0 MHz. At this field strength, the Hall voltage on theprobe is 0.543 mV when the current through the probe is 0.15 mA. Later, when anunknown magnetic field is measured, the Hall voltage for the same current...

Consider a proton cyclotron with a radius 3 meters, a magnetic field B=0.6 T and a voltage source with an amplitude V = 10 kV. What is the maximum energy in joules the protons can reach? To reach the same energy using a single DC potential, how many volts would be required? How long would it take for a proton starting at rest to reach this energy? (hint how much work is done on the proton in each full orbit?)...
