A new magnetic imaging device can "see" the electric current flowing through batteries as clearly as X-rays or MRI scans see inside the human body — and it could even replace X-rays or MRI scans in medical imaging someday.
The device detects electric current by measuring its magnetic field, according to a video report by DigInfo News. That creates images that can show the dead spots in batteries during charging or discharging, and could even lead to better designs for higher battery performance in electric cars, laptops, smartphones and other gadgets.

Such magnetic imaging could also replace the bulkier MRI scanners that require patients to lie still inside imaging chambers, said Kenjiro Kimura, an engineer at Kobe University in Japan. But Kimura first plans to reach out to electronics companies and auto makers through Kobe University's Integral Geometry Instruments.
