Imagine if a doctor could remotely do a non-invasive, highly precise medical procedure on her patients using a tiny robot, or ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new ...

Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

Any movement of a conductor through this magnetic field does indeed produce a force on the electrons within it. But this force redistributes the electrons, generating another field that exactly ...

Drugs and other treatments can be quite effective at killing cancer cells, yet many fall short as they struggle to penetrate ...

A theoretical study demonstrates magnetic force lowers blood pressure fluctuations and stabilises flow, setting the stage for ...

This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

With forefinger (magnetic field) pointing left to right, and second finger (current) pointing down, your left thumb (force) will point towards you. This is the direction in which the force acts.

We have this same problem with electric and magnetic fields. Depending on your reference frame, what appears to be a magnetic force from one spot appears to be an electric force from another.

MFM image reflects the stray field caused by the domains in the surface layer. (Image: Wikimedia Commons, CC-SA 4.0) MFM operates by measuring the magnetic forces between a magnetized probe tip and ...
