*need solution to part C. Gave other answers for supporting information.

Problem 26.72 Constants 1 Periodic Table 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-um-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. I(mA) 10.0 20.0 30.0 40.0 50.0 VH(mV) 0.393 0.750 1.24 1.56 1.97

Explanation / Answer

VH/I = RHB/d

hence slope of VH vs I curve is RHB/d

0.0396=228*10-6*B/50*10-6

B = 8.684*10-3 T
