How to See Electrical Power Producing a Magnetic Field in Action
What we call electric power is voltage multiplied by current. In order to have electric power available to our plugs, we first have to generate it. And our ability to generate electrical energy really means that we convert it from another form of energy. […]

Why We Don’t Have Magnetic Charges
Magnetic fields aren’t visible to us. But if we wanted to see one, it’s as easy as pouring iron filings over a magnet and seeing how they line up from one end of the magnet to the other. […]

The Problem of Generating Electrical Energy
We use generators to get the electrical current we need. Generators are what are used to convert other forms of energy into electrical energy. […]

New Electrical Engineering Series Dives into Edison/Tesla War
Thomas Edison and Nikola Tesla’s electricity feud is legendary. While Edison championed direct electrical current, flowing just one way, Tesla worked on alternating current, which flowed in two directions. This week on Wondrium Shorts, electricity gets ugly. […]

The Evidence on the Existence of Dark Matter
Dark matter neither interacts with light nor absorbs it, and no evidence has been given for this phenomenon. It does exist, but it remains mysterious and invisible. […]

Vera Rubin, the Rotation Curve, and the First-ever Evidence of Dark Matter
Through her studies of the galaxies’ rotation curve with her students, Vera Rubin discovered the first indirect observational evidence of dark matter. […]

Making of the Atomic Clock and the Downsides of Cesium
In 1955, British researchers Louis Essen and Jack Parry used cesium-133 to make the first atomic clock. In their clock, cesium’s unpaired electron acts like a small magnet, interacting with the nucleus in a special way. […]

Which Group 1 Metals Influence Our Everyday Lives?
Lithium is located in the first column and second row of the periodic table. Its place on the table can tell us that although it has a low mass, it can carry large amounts of charge regardless. […]

The Fascinating Qualities of Alkali Metals
When some metals, such as sodium, interact with water, they produce strong bases called alkalines. The term ‘alkali’ itself comes from an Arabic expression used to refer to wood ash heated without oxygen. […]
