About This

• Magnetic wire demonstration: granular iron sand, round granular iron sand replaces old iron chips
• Easy to observe: made of plexiglass for easy observation, distribution of magnetic inductance lines around the magnet
• Working principle: When the magnet is placed on 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 needles" are connected to each other heads and tails, showing the shape and distribution of the magnetic inductive line.
• Physics experiment equipment, learning aids for students, teaching aids and instruments.
