A high school physical magnetic field line simulation device

Abstract

The present invention discloses a high school physics line magnetic force simulation device. The device comprises a box body, the lower side of the box body is connected with a bottom cover through ahexagon bolt, one side, close to the bottom cover, at the internal portion of the box body is provided with an electric blower, one side, close to the electric blower, at the internal portion of the box body is provided with a separator, a transparent plate is arranged at the middle portion of the internal portion of the side wall of the box body, a regulation rotation wheel is arranged at the middle portion of the upper side of the box body, and one side, close to the box body, of the regulation rotation wheel is connected with one end of a plastic connection rod. Wind power generated by theelectric blower is employed to magnetic powder placed at the upper side of a ventilation thin film to be blown into the air to supply an upward force to the magnetic powder to offset the gravity and to be distributed around a bar magnet so as to vividly and visually simulate a magnetic induction line from the angle of the three-dimensional space, the design of the regulation rotation wheel can facilitate regulation and observation of distribution change of the magnetic induction line, and the transparent plate is cooperated with a LED head lamp to facilitate observation.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a high school physical magnetic field line simulation device. Background technique [0002] Magnetic field lines, also called magnetic field lines, are some curves used to vividly describe the magnetic field distribution. People define magnetic field lines as lines tangent to magnetic induction everywhere.
