What Is Magnetism? The Force That Moves Without Touch

Magnetism is a force that pushes or pulls objects without physical contact.
It comes from the motion of electric charges, especially spinning electrons in atoms.
Every magnet has two poles—north and south—that always come in pairs.
Like poles repel each other, while opposite poles attract.
Earth itself is a giant magnet, guiding compasses with its magnetic field.
Magnetic fields are invisible but can be mapped using iron filings.
Electricity and magnetism are linked—electric currents create magnetic fields.
This link powers motors, generators, and much of modern technology.
Strong magnets can even levitate objects using magnetic repulsion.
From fridge doors to MRI machines, magnetism is everywhere in daily life.
