Study Notes

Electric Current Effects

An electric current produces a magnetic field around the conductor.
The flow of electric current through a wire generates heat due to the resistance of the wire.

Magnetic Field and Electric Current

An electric current flowing through a wire produces a magnetic field around the wire.
The strength of the magnetic field depends on the magnitude of the electric current.

Electric Motor Principle

Electric motors operate on the principle that an electric current produces a magnetic field, which interacts with the motor's magnetic field to produce rotational motion.
The interaction between the two magnetic fields generates a torque, causing the motor to rotate.
