✦ Synopsis

For a long time it has been known that heating a phosphorescing substance makes its light die away more rapidly and that the same effect is caused by illuminating it with light different from that which excited it. More recently Gudden and Pohl found that the application of a strong electric field brings about the same result. In this paper it is shown that a strong magnetic field also is effective. No effect is produced by magnetic fields of strength less than 20,000 gausses. Even with the highest attainable strength, 45,000 gausses, the change was much less than that due to the application of a field of IO,OOO volts per cm. The sudden creation of the magnetic field causes the phosphorescing substance to grow brighter, after which there comes a period of decay. Moreover the light emitted by ZnS when the field is turned on is partially polarized perpendicular to the magnetic lines of force.
