Solve the given parts of following problem:
Problem: A Hall Effect probe used to measure magnetic fields is made with a copper bar of thickness 1.60-m. The conduction electron density of copper is 8.47x1028 m3.
Part I: If the current in the bar is 520mA, find the perpendicular magnetic field present when the Hall potential difference is 1.5V.
Part II: If the current in the bar is 520mA, find the perpendicular magnetic field present when the Hall potential difference is 2.0mV.
Please show your results in detailed calculations for above problem.
