When I were but a  PhD student at CERN  we had a 1.5 Tesla magnet - but this
was the second or third biggest magnet in the world, and you could
comfortably set up house inside it. In the equipment barracks next to it
underground (portakabins) the monitors on the computers had to be read by
tilting your head to the side.
