An electric current flows in a straight wire in a direction into the page. As a result, a magnetic field is produced around the wire. Every field line is a circle, although only one field line is drawn. Which row gives the description of the magnetic field?
- Aanti-clockwise; evenly spaced over the whole field
- Banti-clockwise; more widely spaced further from the wire
- Cclockwise; evenly spaced over the whole field
- Dclockwise; more widely spaced further from the wire
