But if you’re willing to trade a large space requirement for a high voltage hazard instead, a magnetic loop antenna might be just the ticket. Loop antennas like these are typically used only for ...

It’s thus worth putting in the effort to make a better antenna, and if you’re not fortunate enough to have a lot of space, your best choice may be a magnetic loop. [Robert Hart] takes us ...

Specialized protein machines called SMC ... They developed a new way to use "magnetic tweezers" by which they could watch individual SMC proteins make looping steps in DNA. Importantly, they ...
