Magnetic

Think you've played around with some strong magnets?:
"The world's most powerful "split magnet" - one that is made in two halves with holes in the middle to observe experiments - has been built in the US."
"It operates at 25 Tesla, which is equivalent to 500,000 times Earth's magnetic field."
What is interesting about this is:
"But the new magnet has holes on four sides that are 6cm tall and 15cm wide - making it possible to shine a laser through a port onto the material inside and study, for example, how it scatters the light. "
"Already, the researchers think they might have seen a phase transition that does not exist in ordinary liquid crystals with long, straight molecules, but apparently does exist with long molecules that are bent in the middle."
