On the modifications of the spectra of iron and other substances radiating in a strong magnetic field

Abstract

Soon after Professor Zeem an announced his important discovery that the spectra lines become sensibly altered in appearance and constitution when the source of light is placed in a strong magnetic field. I determined to examine if the spectra of different substances are equally or similarly affected, and also if the various lines in the spectrum of a single substance are equally or differently affected by the action of the magnetic field.
