About This Product
When current flows the electromagnet pulls the armature so the hammer hits the gong, which breaks the circuit and lets the spring pull it back, and the cycle repeats. The model makes this make-and-break action easy to follow in lessons on electromagnetism and energy conversion. Educational Instrument can arrange export supply of the Bell Demonstration Model to Samoa, Dominican Republic, Iceland, Senegal, Lesotho and Honduras.
