In Chapter 22, we learned that the direction of the electric field about a point charge is radial to the charge. (As in radial inwards, pointing towards the center of a circle, or radially outwards, pointing away from a circle.) What is the direction of the magnetic field surrounding a current-carrying wire? The magnetic field is parallel to the wire. The magnetic field is radial to the wire pointing toward the wire. The magnetic field is directed along concentric circles surrounding the wire. The magnetic field is radial to the wire pointing away from the wire
