Assuming that when a dielectric is placed in a magnetic field a mechanical stress μH^2/8π where μ is the permeability and H is the magnetic field developes on the surface of a dielectric, a theoretical expression for the change of dielectric constant of the medium has been derived when placed in an external magnetic field. As the expected change is extremely small a specially designed magnetic field and a very sensitive system of dielectric constant measurement have been utilized in the present investigation. The results are reported for nitrobenzene, ethyl and methyl alcohol for a radial magnetic field upto 4000 gauss and the experimental results are in close agreement with theoretical predictions.
