Respuesta :
The armature rotates the axle in the magnetic field of an electromagnet, which induces an electric current defined that es the working of an electric generator.
What is an electric generator?
An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
When strong magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.
Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.
