$Measurement of refractive index using a Michelson interferometer$

Magnetic Field • Helm holtz coil • Current provided using simple DC power supply • Able to produce fields of upto 170G/0.017T • Slide on which semiconductor rests is inserted into <strong>the</strong> coil • Average deviation of B from maximum value = 5.4% • Measured using Gaussmeter (axial probe)
