An insulated copper wire is wound on a soft iron core. Current is passed through the coil such that at end ‘A’ the current flows anti- clockwise and a magnetic compass needle placed at other end ‘B’ of the coil. i) What polarity is created at B? ii) How is the magnetic compass affected when current flows through the coil? |
