What is an electromagnet and how does it work? Electromagnets create a magnetic field through the application of electricity. When you introduce the current, either from a battery or another source of electricity, it flows through the wire. This creates a magnetic field around the coiled wire, ...

They work differently to TEMs and SEMs too: they have an extremely sharp metallic probe that scans back and forth across the surface of the specimen. As it does so, electrons try to wriggle out of the specimen and jump across the gap, into the probe, by an unusual quantum phenomenon ...
The piece of equipment that does this, humming with electromagnetic energy as it goes, is called a transformer. Let's take a closer look at how it works!Photo: A typical small electricity transformer supplying houses from the main power grid. Note the cooling fins (those vertical metal ...
Modern quantum physics provides the framework for energy medicine. Einstein demonstrated that matter and energy are interchangeable and therefore our bodies are energy. Matter, then, does not exist in certain places with certainty, but shows tendencies to exist. A particle can also act...
Induction does not involve a transfer of electrons, nor does it involve direct contact. Rather, it uses the principle that "like charges repel and opposite charges attract." Induction occurs with two electrical conductors, because they allow charges to move freely. ...
