Note 2: Maxwell's equations, in differential form, are given by the relations where (a) E, H, B , and D are the vectors of the electric field strength (volts per meter), the magnetic field strength (amperes per meter or oersteds), ......
英文: After deriving the governing equation of motion of these dampers and the theoretical model, we simulated the damping force of the dampers under different electric field strength conditions, and used an electrical hydraulic servo dynamic testing system to 中文: 在不同电场下,模拟阻尼器的阻尼力...
Equation 1.4 describes that the source of an electric field is from the charge density in a given volume, while equation 1.5 denotes that magnetic monopole does not exist. They are collectively known as Gauss’s law. Equation 1.6 or Faraday’s law explains that a time-varying magnetic field ...
