in faraday's experimental conclusion plzzz tell the direction of flow of current and deflection in galvanometer in all it's 5 conclusions????
Following are Faraday’s experiments with the direction of induced currents:
Experiment 1 − Current induced by a magnet
The relative motion between the magnet and the coil generates electric current in the coil. The current so generated is called induced current.
Experiment 2 − Current induced by a current
When the bar magnet is replaced by a second coil C2 connected to a battery, the steady current in coil C2 produces a steady magnetic field. As coil C2 is moved towards coil C1, the galvanometer shows a deflection. This indicates that electric current is induced in coil C1. When C2 is moved away, the galvanometer shows a deflection again, but this time in the opposite direction. The deflection lasts as long as coil C2 is in motion.
Experiment 3 − Current induced by changing current
The figure shows two coils C1 and C2 held stationary. Coil C1 is connected to galvanometer G while the second coil C2 is connected to a battery through a tapping key k.
It is observed that the galvanometer shows a momentary deflection when the tapping key k is pressed. If the key is held pressed continuously, there is no deflection in the galvanometer. When the key is released, a momentary deflection is observed again, but in the opposite direction.
