Physical experiment magnetic field simulation device

The utility model relates to the technical field of physical experiments, in particular to a physical experiment magnetic field simulation device which comprises a shell, the inner side of a first friction sleeve is in contact with a supporting rotating rod, the other end of the supporting rotating rod is fixedly connected with a threaded rod, the outer side of the threaded rod is spirally connected with an installation rod, and the upper end face of the installation rod is fixedly connected with a fixing plate. A second friction sleeve is embedded in the inner side of the bottom of the display plate; a transparent observation plate is arranged on the inner side of the display plate; a connecting block is fixedly connected to the lower end surface of the transparent observation plate; a friction convex block is fixedly connected to the outer side of the connecting block; and the outer side of the friction bump is in close contact with the second friction sleeve, so that the transparent observation plate can b
