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 ...

When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges ...

Protein crystallisation, a cornerstone technique in structural biology, is increasingly being refined through the controlled application of external electric and magnetic fields. By precisely ...

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 ...

"...a personal field ... as portrayed in many science fiction movies and comic books, that is invisible to the naked eye—that will take some doing." Reading time 5 ...

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 ...

Scientists studying Earth's magnetic field have discovered that its electric heartbeat flows in the opposite direction from what long-standing models predict. Earth is surrounded by a vast magnetic ...
