Akito observes the emf as the coil rotates in the magnetic field. For what orientation of the area vector does he say the magnitude of the induced emf is least?
- "When the area vector is perpendicular to the field direction."
- "When the area vector is parallel to the field direction."
- "When the loop is at 30° to the field direction."
- "When the loop is at 45° to the field direction."
