The magnetic field lines around a straight conductor carrying current are concentrated circle whose centre lies on the wire. When the current in the wire flow in the upward direction then the lines of the magnetic field are in the anti clock direction if the direction of a current in the wire is reversed the direction of the magnetic field line aasu gets reversed. The magnitude of magnetic field produced by a state carrying conductor wire at a given point is: Proportion to the current passing in the wire Inversely proportional to the distance of that point from the wire. So greater the current in the wire strong will be the magnetic field produced and greater the distance of a point from the current carrying wire speaker with the magnetic field produced at the point in fact as we move away from the great a conductor wire the concentrated circles around it is present in magnetic field then becomes larger and larger in indicating that increasing strength of a magnetic







field.
