### Part 1: Directional Relationship between B-field and Magnetic Force

In this section, a charged particle is moving through a magnetic field (B-field) and experiences a magnetic force (FB > 0). The B-field vector is depicted with a single arrow at 50°, representing the direction of the magnetic field. Students are tasked with selecting all vectors that could represent the magnetic force:

- **Magnetic Force Vectors**:
  - Vector at 100° (selected)
  - Vector at 50°
  - Vector at 45° (selected)
  - Vector at 80°
  - Horizontal vector (selected)
  - Vector at 40° (selected)

**Explanation**: Vectors in perpendicular orientations often cause the observed magnetic force according to the right-hand rule.

### Part 2: Directional Relationship between Current and Magnetic Force

Here, a current-carrying wire is placed in a B-field and experiences a magnetic force (FB > 0). The magnetic force vector is given at 70°. The task is to choose arrows that could represent the current direction:

- **Current Direction Options**:
  - Vector at 20°
  - Vertical vector (selected)
  - Vector at 70°
  - Vector at 40° (selected)
  - Vector at 45°

**Explanation**: The selected vectors illustrate potential current directions that align with the given magnetic force based on the right-hand rule.

### Part 3: Directional Relationship between Velocity and B-field

A charged particle moves through a B-field and experiences a magnetic force (FB > 0). The velocity vector is shown at 30°. Students choose vectors that might represent the B-field:

- **B-field Vectors**:
  - Vector at 80°
  - Vector at 80°
  - Vector at 30°
  - Vertical vector (selected)
  - Vector at 40°
  - Vector at 60°
  - Vector at 60° (selected)
  - Vector at 30°

**Explanation**: Potential B-field vectors are determined based on their perpendicular relationship to the velocity vector, effectively utilizing the right-hand rule.
