When current in current-carrying conducor is increased
magnetic field around it decreases.
magnetic field around it increases.
magnetic field around it remains same.
magnetic field around it first increases then decreases.
When a current flows in a conductor, a magnetic field is produced around it. On increasing current in conductor, magnetic field also increases.
When we change the direction of current in a conductor, the magnetic field line around it
_________is the pattern of magnetic field around a straight current carrying conductor.
