To generate the magnetic field researchers in Japan built a sophisticated device capable of electromagnetic flux-compression (EMFC), a method of magnetic field generation well-suited for indoor operations. Using the device, they were able to produce a magnetic field of 1,200 teslas, sustain it for 100 microseconds, thousands of times longer than previous attempts, and control the magnetic field so it didn’t destroy their equipment like some past attempts to create powerful fields. The research could lead to powerful investigative tools for material scientists and may have applications in fusion power generation… read more. Open Access TECHNICAL ARTICLE
Sparks fly at the moment of activation. Four million amps of current feed the megagauss generator system, hundreds of times the current of a typical lightning bolt. Image: ©2018 Shojiro Takeyama
