The magnetic effect of electric current is one of the essential effects of electric current in use, without which we would not be able to have motors in today’s world. Magnetic lines of force or magnetic field lines can be used to understand the magnetic field created by a current-carrying wire. Magnetic field lines surrounding a straight current-carrying conductor have the shape of concentric circles, with the center at the conductor’s axis.
Final Answer:
The magnetic effect of electric current means the formation of a magnetic field surrounding an electric current flowing in a wire.
