Step into the invisible world of magnetic forces! Move magnets freely around the interactive workbench to feel how pull strength changes with distance, watch iron filings trace magnetic field lines, and test which real-world objects snap to your magnet.
Magnetic poles, inverse-distance force, ferromagnetic metals, and hands-on science tips.
Every magnet on Earth has two poles: a North pole (N) and a South pole (S). Even if you cut a magnet in half, each piece creates its own North and South poles.
Opposite poles attract (North pulls South), while like poles repel (North pushes North away, and South pushes South away).
Magnetic force gets dramatically stronger as you get closer. When a magnet touches ferromagnetic iron, it snaps tightly and temporarily magnetizes it.
Only certain metals called ferromagnetic metals (Iron, Nickel, and Cobalt) stick to magnets because their atomic domains line up with magnetic fields.
Not all metals are magnetic: aluminum soda cans, gold rings, and copper wires do not have ferromagnetic atomic alignment, and neither do plastic, wood, or glass.
Earth itself is a giant magnet with a molten iron core, which is why compass needles always point towards the magnetic North Pole.

It is a free interactive science sandbox for beginners to experiment with magnetic attraction, repulsion, field lines, and materials.
You can drag the magnet freely with your finger or mouse to watch magnetic items accelerate, snap onto the pole, and get carried around.
Two North poles (or two South poles) repel and push away from each other because their magnetic fields resist overlapping.
Opposite poles have complementary magnetic field lines that loop smoothly from North to South, drawing the magnets together.
No, only ferromagnetic metals like Iron, Steel, and Nickel stick to magnets. Aluminum, copper, and gold are not attracted.
Iron filings align with the invisible magnetic flux lines radiating out of the North pole and looping into the South pole.
