A currently trending question on Skeptics.se references a website that makes the claim that:
In Yuri Gagarin’s historic flight to space, he returned in near critical condition after only one hour and forty-eight minutes in space. Clearly, there was some vital element missing in space that we receive on earth. Yuri had plenty of food, water and oxygen and since the flight was less than 2 hours, he only needed oxygen. The critical missing element appears to be the earth’s magnetic field. Since that first flight, pulsed magnetic devices have been used in every space suit and space station.
Ignoring the statements on Yuri Gagarin's health and just focusing on the question of "pulsed magnetic devices":
- Has there been an instance of a space suit / space station that does not generate a magnetic field?
- If this is not the case, and a magnetic field is generated by the suit / station, is this generated by a specific device (that could be called a "pulsed magnetic device") with the intention of correcting some medical condition?
