1902. No. II. ON A NEW ELECTRIC CURRENT BREAKER. 



This third coil can practically be arranged in two oppositely wound 

 parts, over the two halves of the ring, in such a way that the highly 

 tensioned poles lie diametrically opposite one another. The two halves 

 of this tertiary coil then act in parallel. When the secondary current 

 is broken at the numerous contacts, li, the primary current must suddenly 

 magnetise the iron ring, and then an intense electromotive force will be 

 induced in the tertiary coil.
