Experiment 6 Electromagnetic Induction

The experiment is simple. We studied the relationship between a moving magnet and the current it induces in a wire specifically a solenoid.. we use the device called the galvanometer. The deflection of the needle in the galvanometer shows the magnitude and the direction of the current induced. We saw that the deflection of the galvanometer is very unnoticeable when we move the magnet towards the galvanometer slowly. When we drop the magnet in free fall towards the solenoid we saw a large deflection. Furthermore, we saw bigger deflection when we inserted another solenoid and iron bar inside the bigger solenoid. There are other ways to induce current like changing the current in the wire itself. By turning on and off the power source connected to the solenoid with another solenoid inside, we also observed deflection in the galvanometer.
