Three-Dimensional Magnetic Field Line Demonstrator with Hoof Magnet and Bar Magnet Physical Magnetic Field Demonstration Experimental Equipment Three-Dimensional Magnetic Line Demonstrator

1. PURPOSE:The three-dimensional magnetic line demonstrator is mainly used for the teaching of physical magnetic field in middle schools. It ly displays the direction of the magnetic field at each point in the space around the magnetic field, the direction of the magnetic line of induction, and the formation of the line of magnetic field.2. STRUCTURE:The instrument consists of a bar magnet, a hoof magnet, six rectangular transparent magnetic induction plates, a crescent-shaped transparent magnetic induction plate and a fixed bracket.3. HOW TO USE:1. During the demonstration, shake the demonstrator several times to make the small iron sheets arranged irregularly, pull out the semicircular movable plate, insert the hoof-shaped magnet, and then install and gently tap the surface of the plate, the small iron The film shows lines of magnetic induction in the magnetic field.2. When using bar magnets to experiment, just adjust the semicircular plate to an I-shaped plate.4. MAINTENANCE:1. Avoid the magnetic field when using, so as not to affect the effect.2. The instrument should avoid collision with hard objects and contact with organic solution to avoid damage.

• The three-dimensional currency demonstrator with magnetic induction is mainly used in the teaching of physical magnetic field in middle schools, and visually displays the direction of the magnetic field at different points in the space around the magnetic field and the formation of the direction and direction of the magnetic flux.
• The instrument consists of a ribbon magnet, a latch magnet, six rectangular transparent magnetic induction plates, a crescent-shaped transparent magnetic induction plate and a fixed bracket.
• During the demonstration, shake the demonstrator several times to make the small iron pieces look irregular. Pull out the movable board in a semicircle, insert the cross-shaped magnet, and then paste the surface of the board and tap it lightly. Magnetic core currency appears in a magnetic field.
• Demonstration experiment used to explain the existence of magnetic field and the spatial distribution of magnetic field lines
• If you are experimenting with ribbon magnets, placing the semicircular plate on top of the I-shaped plate is sufficient.
