Question:

Indium antimonide (InSb) is a semiconductor commonly used in Hall-effect devices because of its relatively large Hall coefficient. A magnetic-field sensor is made from a 50?m-thick strip of InSb, with Hall coefficient 228 cm³/C. The table below shows the Hall potential as a function of current when the sensor is oriented with its current perpendicular to the unknown magnetic field. Plot the Hall potential against a quantity that should give a straight line, determine a best-fit line, and from it find the magnetic field strength.
