About This

• The instrument consists of a bar magnet, a trapezoidal magnet, a transparent magnetic induction board, and a fixed bracket
• The direction of the magnetic field at each point and the direction of the magnetic line of induction and the formation of the magnetic line of induction.
• The demonstrator is used for the teaching of physics magnetic field in middle school, vividly showing the space around the magnetic field
• High-grade plastic, strong and durable. Novel and beautiful, the effect is obvious.
• During the demonstration, shake the demonstrator several times to make the small iron pieces irregular, pull out the semicircular movable plate, insert the hoof-shaped magnet, and then install and gently tap the plate surface, the small iron piece is on Magnetic lines of induction appear in the magnetic field.
