Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.

Question

**Q3.** As the magnet moves closer, the flux enclosed within the coil increases. Why?

The coil wants to oppose this change. Thus, it responds with an *induced* current \( I_{\text{induced}} \) to create an opposing induced magnetic field \( B_{\text{induced}} \).

*Diagram Explanation*:
The diagram shows a side view of a coil. The front of the coil is labeled, and an arrow representing the induced current \( I_{\text{induced}} \) is shown moving counter-clockwise around the coil. Another arrow points from the interior of the coil outward, labeled \( B_{\text{induced}} \), indicating the direction of the induced magnetic field opposing the change in flux.

*Note*: In this situation, if \( B_{\text{induced}} \) was in the opposite direction, it would add to the original field and increase the energy of the system!

**Q4.** If the same magnet moved away from the coil, insert arrows to indicate the directions of \( B_{\text{induced}} \) and \( I_{\text{induced}} \) below. Explain the reasons for your choices in the space below. Think in terms of Lenz’s Law.
