Electromagnetism Principles: Solenoid and U-Magnet Pole Interactions #3851468 (License: Personal Use)

The image displays four labeled configurations (A-D): A and B are straight solenoids with current direction indicated by arrows, showing how winding direction and current define N/S poles; C and D are U-shaped electromagnets with opposite pole orientations, illustrating attraction and repulsion based on adjacent pole alignment. Each diagram includes magnetic pole labels (N/S) and current flow arrows for clarity.

Used in physics education resources, especially introductory electromagnetism lessons, to teach the right-hand grip rule, magnetic polarity in coils, and interaction between electromagnets. Matches user intent for visual learning of magnetic field principles.
