About This

• This electromagnetic demonstrator professionally presents the physical effect of DC current generating magnetic field around conductors, and intuitively verifies the correlation between magnetic field distribution direction and current flow direction for physics electromagnetism teaching research.
• Integrated with three core demonstration units: linear current, circular current and solenoid magnetic field. Adopts multi-turn coil design instead of single wire, effectively boosts magnetic induction intensity and makes magnetic field induction lines clearer for observation.
• Adopted high-transparent integral material shell, the internal magnetic field changes and coil structure are fully visible. It can perfectly verify the right-hand spiral rule, and the magnetic needle deflection changes obviously when reversing the current direction.
• Comes with complete supporting accessories including small magnetic needles, connecting wires and iron powder. Compact size 250×182×78mm and 250g lightweight body, easy to place on experimental bench, suitable for classroom demonstration and laboratory daily use.
• Simple assembly and intuitive operation. With standardized use and maintenance methods, avoid friction to keep transparency; cut off power in time after induction lines appear to prevent coil overheating, support long-term repeated experimental use.
