List of Demos Thrust bar magnet through coil and measure the current in galvanometer. Increase number of coils Compare simple electric circuit- light bulb and battery with bar magnet and coil. Coil connected to AC source will induce current to light up bulb in second coil. Gray magnet, solenoid, and two LED’s, push and pull, shows that different LED’s light up. Lenz’s Law Hanging aluminum ring with gray magnet. Lenz’s Law Jumping aluminum ring from core of solenoid powered by an AC source. Press the button. Slowing down of swinging copper pendulum between poles faces of a magnet. Eddy Currents Two large copper disks with two magnets Neodymium magnet swinging over copper strip. Eddy currents Neodymium magnet falling through copper pipe. Cool with liquid nitrogen. Eddy currents Inductive spark after turning off electromagnet. Inductance.
