Question

use the diagram of a magnetic field to identify the points being described. the positive (n) pole of the magnet: the negative (s) pole of the magnet: the strongest push or pull on a charged particle at a distance from the magnet: the weakest push or pull on a charged particle at a distance from the magnet.

Explanation:

To solve this, we analyze the magnetic field diagram:

1. Positive (N) Pole of the Magnet

Magnetic field lines exit the North (N) pole. In the diagram, field lines exit from \( \boldsymbol{E} \), so \( E \) is the N pole.

2. Negative (S) Pole of the Magnet

Magnetic field lines enter the South (S) pole. In the diagram, field lines enter \( \boldsymbol{D} \), so \( D \) is the S pole.

3. Strongest Push/Pull on a Charged Particle

Magnetic field strength is strongest near the poles (field lines are densest here). Among the points, \( B \) (near \( D \), the S pole) or \( E \) (near \( E \), the N pole) is strongest, but \( B \) is closer to the pole (denser lines), so \( B \) has the strongest force.

4. Weakest Push/Pull on a Charged Particle

Magnetic field strength is weakest far from the poles (field lines are sparsest here). Among the points, \( A \) or \( C \) are far, but \( A \) and \( C \) are similar—\( A \) (or \( C \)) has the weakest force (sparser lines).

Final Answers:

• Positive (N) pole: \( \boldsymbol{E} \)
• Negative (S) pole: \( \boldsymbol{D} \)
• Strongest force: \( \boldsymbol{B} \)
• Weakest force: \( \boldsymbol{A} \) (or \( \boldsymbol{C} \), depending on distance; \( A \) is a common choice)
