A Hall probe serves to measure magnetic field strength. One such probe consists of a poor conductor 0.135 mm thick, whose charge‑carrier density is 1.01×1025 m−3. When a 1.97 A current flows through the probe, the Hall voltage is measured to be 4.29 mV. The elementary charge ?=1.602×10−19 C. What is the magnetic field strength ??
