how registers stock binary values?

Just a matter of curiosity, how binary values are stuffed in processor memories ? is it the same way as the ram does ? what is that ? magnetism ? Well I'd like to know since I picture signals has an electric flow, if the latter is true h开发者_如何转开发ow could a flow be stocked within a memory space ? thanks for the head-ups !
