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...
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?...
A Hall probe serves to measure magnetic field strength. Such a probe consists of a poor conductor 0.159 mm thick, whose charge-carrier density is 1.31 × 1025 m–3. When a 2.29-A current flows through the probe, the Hall voltage is measured to be 3.67 mV. What is the magnetic field strength?
5.3. A Hall effect device is used to measure the strength of an external magnetic field. The device is oriented in the way described in Fig. 5.1. It is made from a cube of p-type silicon with hole concentration cm3 where the length of each side of the cube is 1 mm current of 3 mA is applied through the device. The voltage measured across the device is 2.4 mV. Find the strength of the external magnetic flux density, |B|.
A Hall effect probe used to measure magnetic fields is made with a copper bar of thickness 2.50 μm . The conduction electron density of copper is 8.47x1028 m−3. Part A If the current in the bar is 440 mA , find the perpendicular magnetic field present when the Hall potential difference is 2.0 V .

In a probe that uses the Hall effect to measure magnetic fields, a 12.8 A current passes through a 1.80 cm -wide 1.32 mm -thick strip of sodium metal. If the Hall emf is 1.90 μV , what is the magnitude of the magnetic field (take it perpendicular to the flat face of the strip)? Assume one free electron per atom of Na, and take its specific gravity to be 0.971.
