Introduction to Electricity And Magnetism Electricity is basically the presence and motion of charged particles. On the other hand, magnetism refers to the force which the magnets exert when they attract or repel each other. Thus, we see how different they are from each other. After studying the...
How does electricity cause magnetism? What is a non-uniform magnetic field? What is the Earth's magnetic field? What does Earth's magnetic field do? What is the electromagnetism right-hand rule? Is electricity related to magnetism? Why does magnetism exist?
Additionally, ferrimagnetism can be thought of as a combination of ferromagnetism and antiferromagnetism due to many similarities shared among them, but it still has its own uniqueness, according to the University of California, Davis. Electricity and magnetism Infographic showing how Fleming's right-...

┌──┐│魁《│└──┘ 图3在均匀磁场中电子的运动轨迹 上面是对固体中电子在磁场中运动的经典处理。按照量子理论,电子在磁场中作回旋运动的轨道是量子化的,因而电子沿垂直于磁场方向运动的能量分量必然也是量子化的。因此,在有磁场时,电子的准连续能谱变成一些高度简并的等距分立能级。这些分立能级称作朗道...
