A controversial new study has claimed that it is possible to generate electricity using the Earth's rotation, its magnetic field, and a surprisingly simple device. If replicated, that could be pretty ...

When an electric current passes through a metal ... which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the geomagnetic ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

"Among various materials, helimagnets are particularly interesting because they exhibit chirality through their magnetic structure ... where electric current flows more easily in one direction ...

Nearly two centuries after Faraday's failed attempts, scientists have demonstrated that Earth's continuous spin can directly ...

Where does the force come from? Electric currents and magnetic fields are closely related. If you have one, you often have (or can make) the other. The braking force in the demonstration is due to ...

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

it moves parallel to the magnetic field, producing no force. This would tend to make the motor come to a stop, but two features allow the coil to continue rotating: This means that the current in ...

Magnetic Force Microscopy (MFM) is a scanning probe microscopy ... and in-situ MFM under external stimuli (e.g., magnetic fields, temperature, and electrical currents). These advancements will enable ...
