For demonstrating the procedures, but also useful for remagnetising old magnets, compass needles and for general use as a powerful electromagnet. It comprises a solenoid wound with insulated copper wire and mounted on a base complete with switch and 4 mm terminals. Solenoid 250 x 35 mm length x diameter. Operating voltage 12 V a.c. or d.c. at 6 A. Magnetising possible by a.c. or d.c. However, De-magnetising can be accomplished by a.c. only. |
