Electromagnet Polarity and Right-Hand Rule Diagram Explained #93693 (License: Personal Use)

The image displays four configurations: two straight solenoids (A and B) and two U-shaped electromagnets (C and D), each with wire winding direction and current flow indicated by arrows. In A and C, current enters at the left, producing a north pole on the left end; in B and D, reversed current yields a south pole on the left. This demonstrates the direct relationship between current direction and magnetic polarity via the right-hand grip rule.

Used in educational physics content-textbooks, online lessons, or lab guides-to teach electromagnetic induction, solenoid behavior, and magnet polarity determination. Matches user intent for visual learning of foundational electromagnetism concepts.
