### Diagram Description: Inducing Electromagnetic Current

This diagram illustrates the concept of electromagnetic induction using a magnet and a coil.

- **Components:**
- A bar magnet is depicted vertically with its north (N) and south (S) poles labeled. The magnet is oriented with the south pole at the top and the north pole at the bottom.
- An arrow adjacent to the magnet indicates movement upward, suggesting that the magnet is moving away from the coil.
- Below the magnet, there is a loop labeled "coil," representing a conductive coil.

- **Coordinate System:**
- A three-dimensional coordinate system is present in the diagram, labeled with x, y, and z axes. This helps to establish spatial orientation:
- The x-axis is directed horizontally.
- The y-axis is oriented vertically.
- The z-axis extends perpendicularly to both the x and y axes.

**Explanation:**

This setup is used to demonstrate Faraday's Law of Electromagnetic Induction. As the magnet moves up away from the coil, a change in magnetic flux through the coil occurs. According to Faraday's Law, this change induces an electromotive force (EMF) and consequently a current in the coil if it is part of a closed circuit. The direction of current induced in the coil can be predicted using Lenz’s Law, which states that the direction of the induced current will be such that it opposes the change in magnetic flux.
