you can produce magnetic field around a conductor just by passing current through it and you can increase the magnetic field by increasing the number of turns of the conductor

a) when current increase magnetic field also increase
b) if flow of current reverse then the direction of magnetic field also reverse
c) number of turn in coil increase, magnetic fileld also increase
b) if flow of current reverse then the direction of magnetic field also reverse
c) number of turn in coil increase, magnetic fileld also increase
