Question
Position the solenoid so that its left end is at about the 0 cm mark. Move the pickup coil (short) somewhere inside the solenoid. Turn on the DC power supply and set the current to 6 A Turn on the B-field lines. The density and darkness of those lines at any point is a measure of the field at that point. The green triangles on the central axis indicate the direction of the B field entering or exiting that end of the solenoid. The coil, which is connected to the computer interface, now has a magnetic field passing through it. Above the bottom graph select the 5 mV radio button to set the Pickup Emf graph scale. Start data. The bottom graph, "Pickup Emf (V)," displays the induced emf in the pickup coil. Question: What is its value? Why do you get that reading? Take a screen shot and attach to your lab report.Explanation / Answer
As the pickup coil is placed at the end the number of turns at end become zero . So the induced emf (pickup emf) also become zero.
You can place the coil somewhere between and see the results .
