Gamvdout Current Magnetic Field Demonstrator - Physics Teaching Instrument Used in Physics Experiment Equipment

Purpose: To demonstrate the phenomenon that a magnetic field is generated around a conductor when a DC current passes through it, and the relationship between the direction of the magnetic field and the direction of the current. This instrument is made of transparent material, please avoid friction on the surface to maintain its transparency. Structure: The current magnetic field demonstrator consists of three parts: linear current magnetic field, annular current magnetic field, and solenoid magnetic field demonstrator. All of them use multi-turn coils instead of single-strand wires to increase the magnetic induction intensity and enhance the demonstration effect. During the demonstration, after the magnetic flux lines are formed, the power supply should be cut off to avoid overheating and damage to the instrument. After the experiment, use a brush to clean the iron powder.
