Electromagnets generate a steady magnetic field when an electric current is run through them, and they come in three main types. Resistive magnets are made from everyday metals like copper, making them relatively simple while offering flexible and fast control of the magnetic field. They are, how...
It is also a good idea to store NdFeB magnets away from electronic devices, as the strong magnetic field of the magnets can interfere with their operation. 11. Can you quote me your best price? NdFeB magnets can vary significantly in price, the cost be affe...

The only explanation that fitted the observations of the supernova following GRB 111209A was that it was being powered by a magnetar—a tiny neutron star spinning hundreds of times per second and possessing a magnetic field much stronger than normal neutron stars, which are also known as radio...

A consortium of seven partners, led by the Donders Institute for Brain, Cognition and Behaviour (Radboud University), has received a €19 million Roadmap grant from the Dutch Research Council (NWO). It will be used to build the world's first MRI scanner
First, there is a difference between strength and durability-the strongest fiber is not necessarily one that lasts the longest. Linen is a very strong fiber, but a linen shirt's cuffs start to show wear more quickly than garments made from "weaker" fibers. 展开 年份: 2011 ...
10. When the magnetic field is at its strongest, and sunspots at their most plentiful, they cluster close to the equator. 当磁场最强,太阳黑子最丰富的时候,它们会聚集在赤道附近。 youdao 11. This figure was made up of 5,893 women and 3,220 men, with the strongest associations being with ...
In general, stellar flares occur when magnetic-field lines in a star's atmosphere tangle, snap and reconnect, releasing a powerful gout of radiation that's visible across the entire electromagnetic spectrum. On the sun, flares may be accompanied by towering loops...
