A magnetic field is a force field that is created by magnetic dipoles and moving electric charges, and it exerts a force on other nearby moving charges and magnetic dipoles. The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. If the current is flowing in an electric circuit from South to North direction and a magnetic compass is placed over the conducting wire, the needle of the compass deflects in the direction of west. When electric current passes through a wire, the current-carrying wire behaves like a magnet and this is called the magnetic effect of current. The magnetic effect of current is utilised in making electromagnets, electric bells, telephone instruments, electric fans, electric motors, loudspeakers and toys etc. Read through the presentation to get more points.
