Question

# 2. Describe what happens when you make the following changes, and explain why, using Faraday's and Lenz's laws. Explain not only the magnitude of the effects but also their direction

(for example, the direction the needle moves in the pickup coil indicator). Pay attention also to what reaches its maximum value when. That is, note (and explain)at what point in the current cycle of the electromagnet the voltage indicator is at its (a) Using the DC current sSource: i. The electromagnet is moved closer or farther from the pickup coil, when po-sitioned on both the right and left sides of the pickup coil. ii. You change the electromagnet battery voltage iii. You change the number of loops in the electromagnet iv. You change the number of loops in the pickup coil v. You change the area of the pickup coil (b) Using the AC current source: i. The electromagnet is positioned closer or farther from the pickup coil, on both the right and left sides of the pickup coil, and also positioned inside the pickupcoil. ii. You change the Current Supply amplitude iii. You change the Current Supply frequency iv. You change the number of loops in the electromagnet v. You change the number of loops in the pickup coil vi. You change the area of the pickup coil
