text: At each point around the magnet, the magnetic field has both a strength and a direction.
text: For a long straight wire, the magnetic field has a direction that encircles the wire on a plane perpendicular to the wire.
text: Magnetic fields have both a magnitude and a direction (represented by the arrows in Figure 1).
text: The magnetic field has direction as it is a vector quantity.
text: A magnetic field is a vector, which means it has magnitude and direction.
text: Remember that magnetic fields have both magnitude and direction.
