Made by coiling a wire several times around an iron core, magnetic amplifiers worked using saturation. By passing a small direct current through it, the iron core could be forced in and out of saturation. In a saturated state, it would allow AC current to pass through, otherwise, it blocked it. Although central to Germany’s WW2 military hardware, like the V-2 rocket, magnetic amplifiers were largely too inefficient to use until the 1950s, when the Germans created a pure fifty/fifty nickel-iron alloy that made them more compact, efficient, and reliable.

Growing stronger and losing weight without putting in the effort seems like a fairytale, right? Electrical muscle stimulation might make the dream come true. During EMS, a full-body suit sends out electric charges that stimulate your muscles as if you’ve actually worked out. Older people, in particular, are reaping the benefits. Since they can’t do traditional strength training anymore, EMS is a viable alternative that keeps them healthy and strong. Some evidence suggests that the benefits go beyond strength training; EMS seems to promote cell growth and slow down the ageing process! Read full article here
