Magnetic field

UPDATE: (Science Alert) – New satellite data from the European Space Agency (ESA) reveal that the mysterious anomaly weakening Earth’s magnetic field continues to evolve, with the most recent observations showing we could soon be dealing with more than one of these strange phenomena. The South Atlantic Anomaly is a vast expanse of reduced magnetic […]

Magnetic Fields II-b

Artist's impression of a magnetar. Magnetars are the cosmic objects with the strongest magnetic fields ever measured in the Universe. They are extremely magnetised pulsars – the hot and dense remnants of massive stars that throw off energetic radiation in impulsive bursts and longer outbursts on timescales from milliseconds to years.

Simulations suggest that a relatively simple laser technique could produce femtosecond magnetic-field pulses, which currently are only available at a few major lab facilities.

It may or may not be true for people, but for magnets, opposites really do attract! Magnets – What are magnets? Well,
