Large Columbus Electromagnetic Eddy Currents Egg, Nikola Tesla Science Physics Experiments, Standing up Columbus Egg, DC Motor Induction Tesla Coil, for Teaching, Gifts, Science Experiments Toys

Features

• The Columbus Egg is an egg-shaped metal block, in a rotating magnetic field, the metal egg rotates according to the principle of the long axis and eventually stands due to the gyroscopic effect.
• Together with the concave tray made of high-grade acrylic, the gyroscope will rotate more smoothly and silky smooth with the copper egg.
• Fine winding group, metal bolt fixed defence frame and base plate, high-grade and sturdy.
• Can switch forward and reverse rotation at will, visual demonstration of AC motor rotating magnetic field.
• Used to show and explain the rotating magnetic field model and the principle of asynchronous motor.
