In Faraday's experiment, moving a magnet into or out of a coil induces an electric current, which is detected by a datalogger. The faster the magnet moves, the greater the magnitude of the emf induced. The sign of emf induced depends on whether the magnet is moving toward or away from the coilโ€”reversing as the direction of motion changes. When the magnet is stationary, the needle returns to the center, indicating no induced emf.

This updated simulation allows the user to explore the laws of electromagnetic induction (Faraday and Lenz) by dragging a magnet into and away from a coil. The update adds new features such as an automatically oscillating magnet and a free-falling magnet. TO observe the direction of current flow , a different setup consisting of two LEDs can be shown.
