Your friend says that if you crank the shaft of a DC motor manually, the motor becomes a DC generator. Do you agree or disagree? Defend your position.
To Explain:The motor becomes a DC generator by cranking the shaft of the DC motor manually
Explanation of Solution
Introduction:
The pair of magnets generate a magnetic field around the coil. The movement of the coils cuts the field and induces a voltage in the coil. This helps a DC motor to act as a generator.
By cranking a shaft of the DC motor manually, it converts to a DC generator. This is because the coil induces voltage because of the motion of the coil between the magnets by turning the shaft of the motor manually. So, the DC motor behaves like a generator.
Conclusion:
The magnets generate a magnetic field around the coil and as the coil rotates, it cuts the field and induces the voltage.
