Will see that the battery is encased magnet and coil are connected by an integrated battery, acts as a voltage, which creates a potential difference, with the cycle. Until the cause an electric current flowing in the coil.
It is evident that the batteries are sandwiched between the magnet and the coil are connected by an integrated battery voltage, which acts as a voltage to the circuit. The resulting current flowing in the coils.
The battery was plastered with magnetic coil and are connected by a comprehensive battery at the electromotive force, which creates a voltage to the circuit. To cause electric current flows in the coil.
