When current flows through a wire, it creates a magnetic field around that wire. This is the principle behind electromagnets. 2. The Rules: Opposites Attract Every magnet has two poles: North and South . Attraction: North and South poles pull toward each other.
Two North poles or two South poles will push each other away. 3. The Field magnetic force
Magnetic force isn't limited to the object itself; it extends into the space around it, called a . We visualize this using "field lines" that exit the North pole and enter the South pole. The closer the lines are, the stronger the force. 4. Real-World Impact When current flows through a wire, it creates
