Magnetic Field Around The Magnet of The Magnetic Induction Line Demonstrator Magnetic Lines of Force Demo Set 3D Magnetic Field Demonstrator

PurposeThis instrument is used for middle school scientific experiments to illustrate the distribution of magnetic lines of induction of the magnetic field around the magnet.Structure and PrincipleThis instrument is composed of iron powder box and magnet. The iron powder box is made of transparent plastic, and its inner cavity is rectangular with a proper amount of iron powder. When changing the tilt direction of the box, the iron powder can move in the box.The magnetic field and the magnetic line of induction are invisible. This instrument uses the property of iron powder to be magnetized in a magnetic field to show the shape of the magnetic line of induction. When the magnet is placed in the middle of the iron powder box, the iron powder in the box is magnetized under the action of the magnetic field. Each iron filing in the iron powder becomes a "small magnetic needle". According to the distribution of the magnetic field, the "small magnetic needle". Connected end to end, showing the shape and distribution of the magnetic lines of induction.
