Solution
The correct option is C both magitude and direction, north, south
Magnetic field is a vector quantity, thus magnetic field is a quantity that has magnitude and direction. Magnetic field is a region around a magnetic material or a moving electric charge within which the force of magnetism acts.For every magnet, the magnetic field lines emerge from the north pole and merge at the south pole. They seek the path of least resistance between opposite magnetic poles. In a single bar magnet, they attempt to form closed loops from pole to pole. They never cross one another. They all have the same strength. Their density decreases with increasing distance from the poles. They are considered to have direction as if flowing, though no actual movement occurs. They flow from the south pole to the north pole within a material and north pole to south pole in air.
