A new study is shedding light on why solar radiation is more effective than other forms of energy at causing water to ...

The super-short version of this equation is that there is another way to make an electric field. It's not just electric charges that make electric fields. In fact, you can also make an electric ...

Sunlight’s electric field boosts water evaporation by breaking up molecule clusters at the surface. Hydrogels help form more ...

Now we've got an equation to calculate the electric field generated by any point charge. But let's make this field even easier to picture.

I want to plot the magnitude of the electric field as a distance from the rod for all three methods (the two equations and the numerical method). Here are my starting parameters. Rod length = 0.5 ...

Maxwell’s equations are a set of equations that describe how electric and magnetic fields come to exist, as well as how they interact with each other, electric charges, and electric currents.

Electric and magnetic fields represent certain local tensions or twists in the spacetime fabric. Our research shows that the Lagrangian of electrodynamics is just the Einstein-Hilbert action of ...

In other words, the electric field activates a latent anisotropy in the material, leading to a large effect in the case of equation (2). References Kruglyak, V. V., Demokritov, S. O. & Grundler, D ...

The field equations then give the correct dynamics for the electromagnetic field. Discover the latest in science, tech, and space with over 100,000 subscribers who rely on Phys.org for daily insights.
