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

**Transcription of Educational Material: Magnetic Fields**

1. **Problem Statement: Vector Representation of Magnetic Field**

At each of the four labeled points *(A–D)*, sketch a vector representing the magnetic field around the bar magnet.

![Bar Magnet](#)

Diagram: A single bar magnet with its north (N) on the left and south (S) on the right. Points A and B are located at either end of the magnet, while points C and D are positioned vertically below the magnet, with C directly below the midpoint and D further down.

2. **Problem Statement: Net Magnetic Field with Additional Bar Magnet**

A second bar magnet, identical to the first one, is placed to the left of point A. (See figure below.) At each of the four labeled points *(A'–D')*, sketch a vector representing the net magnetic field.

![Two Bar Magnets](#)

Diagram: Two bar magnets in sequence from left to right. The first magnet has its north (N) on the left and south (S) on the right, followed by the second magnet with the same orientation. Points A', B', C', and D' correspond to positions similar to those in the first question.

3. **Problem Statement: Ranking the Magnitude of the Magnetic Field**

Rank the magnitude of the magnetic field at points A, B, A', and B'. If the magnitude of the magnetic field at any point is zero, state that explicitly. Explain your reasoning. (If you do not have enough information to determine the ranking, explain what information you would need.)
