Geomagnetic generator DK-60 135-270 1 unit

By observing how the geomagnetic field generates electricity, we can learn about the magnetic properties of the Earth. When the hollow coil is manually rotated, an induced current is created by the magnetic field lines of the Earth's magnetic field crossing the coil. The generated current is checked with a galvanometer. The coil can be oriented in any direction in space, allowing the direction of the earth's magnetic field to be observed. Invented by Mr. Akio Nishizawa, former teacher at Toyokawa City Western Junior High School in Aichi Prefecture. 47th All Japan Teachers Invention Exhibition, Japan Patent Office Commissioner's Award Coil: φ600mm, 200 turns Accessories: Compass Size: W800×D300×H725mm Weight: 3.5kg Product code: 135-270
