Demonstration of electromagnetic effects and current detection. A former with terminals and engraved circle marked 0 ? 180? ? 0 figured every 45?, wound with 30 turns of enamelled copper wire, complete with a magnetic needle 75 mm long and a pivot for the needle.
Functionality (NOT MEANT FOR CATALOGUE)
Demonstrates magnetic deflection of a needle caused by electric current through a conductor.
When DC current flows through the coil, it generates a magnetic field that interacts with the magnetic needle, causing it to deflect?showing the presence and direction of current.
