Pixel-art torsion balance in a glass bulb with bright and blackened discs on a hanging wing, a yellow beam of light from the left and a green arrow showing the push, captioned light pushes

In 1900 Pyotr Lebedev showed that light pushes on a mirror, exactly as Maxwell predicted. Here is how big that push is, why it was so hard to measure, how...

A charged particle's glowing helical path wound around a magnetic field line under an aurora

Why Do Charged Particles Spiral in a Magnetic F...

A magnetic field pushes a moving charge sideways, never forwards, so the charge curves into a circle, or a helix if it also drifts along the field. The time per...

Coil and magnet, a crackling AC motor and arcs of field lines in a Victorian laboratory

Faraday, Maxwell and Tesla: Who Did What in Ele...

Electromagnetism was not one inventor’s story. Faraday made induction a laboratory fact, Maxwell turned fields into equations that predicted light, and Tesla patented a practical AC motor. Here is who...

A cutaway copper pipe with a magnet drifting slowly down inside, wrapped in glowing orange eddy-current loops

Why Does a Magnet Fall Slowly Through a Copper ...

Copper isn’t magnetic, yet a strong magnet dropped down a copper pipe falls in slow motion. The reason is Lenz’s law: the currents the moving magnet induces always push back...

A glowing copper coil on a stone table beside a compass and a horseshoe magnet, an electromagnetic wave flowing out into the dark

How Are Electricity and Magnetism Connected? Fr...

Two hundred years ago electricity and magnetism looked like separate curiosities. Then a compass needle twitched, and within fifty years they had become a single theory that also explained light.
