A semiconductor is a material that has electrical conductivity between a conductor and an insulator.
It allows the flow of electric current under specific conditions and is widely used in electronic components like transistors and diodes.
Draw the pattern of the magnetic field lines for the two parallel straight conductors carrying current of same magnitude 'I' in opposite directions as shown. Show the direction of magnetic field at a point O which is equidistant from the two conductors. (Consider that the conductors are inserted normal to the plane of a rectangular cardboard.)
