MAGNETIC FIELDS
Experience the invisible forces that shape our universe
Move your cursor to feel the electromagnetic energy. Watch iron filings dance to the magnetic field lines.
The Science
Field Lines
Magnetic field lines are invisible pathways that show the direction a magnetic force would take. They always flow from north to south poles, creating continuous loops.
Iron Filings
When sprinkled near a magnet, iron filings align themselves along magnetic field lines, revealing the invisible patterns of electromagnetic force.
Electromagnetism
Electric currents create magnetic fields, and changing magnetic fields create electric currents. This fundamental relationship powers our modern world.
Polarity
Every magnet has two poles: north and south. Like poles repel, opposite poles attract. This simple rule governs all magnetic interactions.
