A booming tech start-up economy and a thriving arts and restaurant scene have helped this old Civil war tourist magnet do something that places across the USA have been trying to do for decades:
D c. They re 20-something magnets that don t just survive but thrive. Among those with the highest ratio, several are old-fashioned cities such as Charleston,
MILLENNIAL MAGNETS Some cities have become strong magnets for young adults. For cities over 100,000 people, ratio shows the number of people ages 20 to 29 for every 100 teens.
Overhead Magnet Belt This device consists of a strong magnet with a conveyor belt moving around it.
Eddy Current Separator An electromagnet inside a rotating drum creates a force field at the end of a conveyor belt.
Researchers can then use magnets to lift and suspend the cells as they grow and divide.
Then he built a simple humidity-driven generator out of Legosâa miniature fan a magnet and a spore-coated cantilever.
As the cantilever flips back and forth in response to moisture it drives a rotating magnet that produces electricity.
