FERROMAGNETIC DISTORTION OF A WAVE 



357 



The influence of one fundamental current upon another has been 

 termed mutual crowding. Because of the increased attenuation, and 

 at times because of resulting unbalance or phase shift, crowding 

 becomes important when different frequencies or bands of frequencies
