In a magnetic milestone to make Nikola Tesla proud, scientists have created the strongest controllable magnetic field ever produced. Energy crackled and sparks flew back when physicists from the Institute for Solid State Physics at the University of Tokyo powered up their 400 million amp megagauss generator system. That’s hundreds of times the current of an average lightning bolt. The device was created by University of Tokyo physicist Shojiro Takeyama and his team. And it generated …
