Equipotential Surfaces: These are surfaces where the electric potential is constant. Electric field lines are always perpendicular to equipotential surfaces. Calculating the electric field at a given ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New ...

This video explains how magnets work and how magnetic fields are generated by the movement of electric charges. Magnetic ...

Today's computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

ALMA reveals that gravity reorients magnetic fields in 17 young clusters, aligning them as gas collapses and accelerating ...

Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla ...
