Ring launcher demonstration (Eddy currents). By- Ravi Chhillar @Physics_Hack
Показать описание
Eddy currents are the whirling currents produced in bulk metal when flux linked with the matal changes.
The ring gets polarity opposite to the coil in accordance with Lenz's law. Due to the repulsion between solenoid coil and ring , ring jumps upwards.
