About This

• This professional electromagnetic experimental device can effectively prove that magnetic field exists around energized conductors, and complete various verification tests for linear current magnetic field distribution rules.
• The overall structure is neat and easy to arrange. Lay the instrument flat, place the magnetic needle properly, and adjust the base position when the magnetic needle is static to keep the conducting wire parallel to the magnetic needle smoothly.
• It is applicable to 6V DC power supply for power supply experiment. After power connection, the magnetic needle will swing visibly, directly presenting the phenomenon that current generates surrounding magnetic field.
• Users can apply the right-hand rule to accurately judge the magnetic field direction, and reverse the current direction to observe the synchronous change of magnetic needle deflection direction.
• It perfectly combines theoretical electromagnetic knowledge with practical operation, helping users deeply understand the conversion law between current and magnetic field, ideal for principle demonstration and academic research.
