电磁波是能量的一种,凡是能够释出能量的物体,都会释出电磁波.电与磁可说是一体两面,变动的电会产生磁,变动的磁则会产生电.要点1:麦克斯韦电磁场理论例1关于麦克斯韦电磁场理论.下列说法正确的是().A.稳定的电场产生稳定的磁场B.均匀变化的电场产生均匀变化的磁场,均匀
Electromagnetic wave is a kind of energy, any object that can release the energy will release the electromagnetic wave.Electrical and magnetic can be said to be one and the same, the changeable electricity will produce magnetism, the changeable magnet will generate electricity. Point 1: Maxwell Electromagnetic Field Theory Example 1 on Maxwell’s theory of electromagnetic fields. The following statement is correct (). A stable electric field to produce a stable magnetic field B. The uniform change of the electric field to produce a uniform magnetic field changes, uniform
