Correct the mistakes, if any, in the following statements.

i) The magnetic field is a quantity that has magnitude only.


ii) Outside the bar magnet, the magnetic field lines emerge from the South Poleand merge at the North Pole.


(i) The magnetic field is a quantity that has magnitude and direction.

Explanation: Magnetic field is represented by the magnetic field lines give both the direction and magnitude (the denser the magnetic field lines, the more are its magnitude), so the magnetic field have both magnitude and direction.
