Further developments of the method of obtaining strong magnetic fields

In previous publications the author has described a method of obtaining strong magnetic fields, and also several experimental researches using these methods. The general principle of this method is to obtain a field in a coil for a very short time only—about 1/100 second—thus making it possible to use a great amount of electrical energy without heating up the coil. Powers up to several thousand kilowatts are necessary for obtaining strong magnetic fields. Such large powers are easily obtained for a 1/100 second by means of specially constructed accumulator batteries, which make it possible to obtain fields of over 100,000 gauss in a sufficiently large volume to make investigations on such subjects as the Zeeman effect.
