Consider six wires coming into or out of the page, all with the same current. Rank the line integral of the magnetic field (from most positive to most negative) taken counterclockwise around each loop shown

When a current carrying wire is bent into a circular loop, magnetic field lines around it

Consider a circular loop of wire lying in the plane of the table, let the current pass through the loop clockwise apply right hand rule to find out the direction of the magnetic field inside and outside the loop.

Consider a circular loop of wire lying in the plane of the table. Let the current pass through the loop clockwise. Apply the right hand rule out the direction of magnetic field inside and outside the loop.

A long straiht telephone cable contains six wires , each carrying a current of 0.5 A. The distance between the wires can be neglected. a. If the current in all six wires are in the same direction, what is the magnitude of the magnetic field 10 cm from the cable ? b. If four wires carry current in one direction and the other two in opposite directions, what is the field magnitude at 10 cm from the cable ?
