Study route
9.1. Magnetic current field
The electric current creates a magnetic field; its direction around the direct conductor is determined by the rule of the right hand, and the field painting is examined by magnetic arrow or iron sawdust.
9.2 Electromagnetics
The electromagnetic coil becomes an electromagnetic coil and the Ferromagnetic heart increases the field many times. The magnetic action can be turned on, switched off, and controlled by current.
9.3. Electric motor and generator
The current conductor in the magnetic field is powered by force, and in the engine it creates a torque, and the conductor's motion in the field creates an electric current.
