由第一段内容“When the sun reaches its peak activity, known as solar maximum, its magnetic (磁的) field will reverse (逆转). This happens roughly every l1 years, marking an important stage in the solar cycle. It indicates the halfway point of solar maximum, the height of solar activity,...
Earth is has it's own protective magnetic shield, called the magnetosphere. The magnetosphere blocks much of the harmful solar and cosmic particle radiation. This magnetic field is immense, but actually quite weak, only about 1 Faraday in strength. But did you know that our magnetic field reve...

Why is the magnetic field outside a solenoid zero? When does electron capture happen? When does alpha radiation occur? When does refraction occur? When is the weak nuclear force encountered? About how often do Earth's magnetic poles reverse?
53.It will be by this methodthe correct answer can be obtained. 参考答案: that 54.More important(be) the fact that the reverse current increases exponentially with temperature. 参考答案: is 55.通过改变VBE零点零几伏特,就能极大的改变基极电流。By varying VBE only ___, the base current(基极电...

Why doesn't Venus have a magnetic field? Why are there no moons that orbit Mercury and Venus? Why is Venus the brightest planet? Why will Polaris not always be the North Star? Why does Venus have the highest surface temperature of planets in our solar system?
The non-interacting spin susceptibility is related to the compressibility by χs = χ/(4β) as shown in Fig. 1b with reverse color scale. Fig. 1c shows the magnetization. Even though the Zeeman field is absent, a non-zero Peierls flux can magnetize the system since the spin-up ...
Why does an angle move with the Earth's magnetic field? Why don't we have a way to model gravity? Why is it preferable for airplanes to take off into the wind rather than with the wind? Why do metal poor stars have the most elliptical orbits? From where ...
