Describe the experiments of M. Faraday and the methods of obtaining induction current in them.

At present, the following experiments are the classic Faraday experiments to detect the phenomenon of electromagnetic induction:
The galvanometer is closed to the solenoid. A permanent magnet slides into (or slides out of) the solenoid. When the magnet moves, the deflection of the galvanometer needle is recorded, which means the occurrence of an induction current. With an increase in the speed of movement of the magnet in relation to the coil, the deflection of the arrow increases. Replacing the magnet poles causes a change in the direction of deflection of the galvanometer pointer. Note that the magnet can be left stationary and the solenoid can be moved relative to the magnet.
This experiment uses two coils. One is inserted into the other. The ends of one of the coils are connected to a galvanometer. An electric current is passed through the other coil. The galvanometer needle is deflected when the current is turned on (turned off), changed (increased or decreased), or if the coils move relative to each other. The direction of deflection of the arrow of the galvanometer is opposite when turning the current on and off (decreasing – increasing the current strength).

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
