If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

Through the study of the natural and physical world by using observation, experimentation, and testable explanations, we can ...

Imagine a world without the glow of your screen, the hum of your fridge, or the instant communication across continents.

In this three week storyline unit, students investigate a maglev train and the electromagnetic forces that cause a maglev train to levitate and provide the source of propulsion for the train. The ...

This video explains what magnets are and how magnetic fields are generated through the alignment of atomic structures.

Electromagnetic fields as they would be generated by positive and negative electric charges, both at rest and in motion (top), as well as those that would theoretically be created by magnetic ...

Many theories predict the existence of magnetic monopoles, but experiments have yet to see them. If you chop a magnet in half, you end up with two smaller magnets. Both the original and the new ...

DR. O. HEAVISIDE has investigated (NATURE, April 19) the slow motion of a charged conducting sphere through a uniform electric field, in a direction parallel to the electric force of the field, and ...

Earth’s magnetic field protects the planet from space weather like cosmic radiation and charged particles from the Sun. The ...

The world of nanoscale analysis has been revolutionized by the advent of electrical Atomic Force Microscopy (AFM) modes. New possibilities for measuring electrical properties with remarkable precision ...
