Magnetic field simulation device for physical experiments

The invention relates to the field of magnetic field simulation technology, and discloses a magnetic field simulation device for physical experiments. The device of the invention comprises a fixed base, which comprises a first placement groove, a bearing and an inserted bar. The first placement groove is located at the upper part of the fixed base. Through the arrangement of the fixed base and thecooperative arrangement of the first placement groove, the bearing, the inserted bar, a bearing plate, a first slide rail, a connection base, a second slide rail, a pulley, a support plate and a bearing frame, the magnetic field simulation device for physical experiments makes a user rotate the bearing frame during the using process such that the bearing frame can slide on the second slide rail through the pulley on the support plate, the bearing frame can smoothly rotate, the user can drive a display board by rotating the bearing frame to show the experimental process to people who sit at different angles, and the u
