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.
