When doing a DC operating point simulation (.op) an operating point data label can be created as follows Run the .op simulation; Left-Click on a net (a wire). This creates a new label that can be placed with the cursor. Since the wire is so small, the coil can have thousands of turns and still fit in the slots. The small-gauge wire cannot handle as much current as the heavy-gauge wire in the series field, but since this coil has many more turns of wire, it can still produce a very strong magnetic field. Figure 12-14 shows a picture of a DC shunt motor. The changing current in the solenoid produces a changing flux in the loop. By Lenz's law there will be an induced current and field to oppose the change in flux. We assume that the solenoid is long enough such that there is not field outside the solenoid, and therefore the flux through the cross section of the solenoid is the flux through the ... We will now look at three examples of current carrying wires. For each example we will determine the magnetic field and draw the magnetic field lines around the conductor.
