      Magnetic Permeability

      Magnetic Permeability is a term refers to the ability of a material to gain or maintain magnetism. When certain materials are placed in a magnetic field they become magnetized.  For example, when you take a piece of iron and rub it on a substance already magnetized or a magnet, it will become magnetized and have a

      How Laser Hair Removal Works

      Laser hair removal, as its name suggests, is using a laser to remove any hair that is unwanted. The majority of the process is done with a thin light beam of laser passing through the area of the skin that is being treated. Within the skin, specifically the dark pigment, also known as the melanin

    • Earth Cooling Tubes

      Earth Cooling Tubes

      Earth cooling tubes present an alternative for controlling temperature within residential and office buildings as well as greenhouses and other structures requiring temperature regulation. These tubes run underground and alter air’s cooling or heating temperature before it is allowed into a home or office. En route, the air releases its heat to the surrounding soil

    • Electromotive Force

      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • Air Exchangers

      Air Exchangers

      An air exchanger is a device that transfers stale air from inside a home to outside, and fresh air from outside to the inside. Air exchangers are often large and built directly into a home’s foundation in order to provide maximum fresh air levels at all times. This is important because indoor air is often

    • What Causes Optical Illusions?

      What Causes Optical Illusions?

      In simple terms, an optical illusion is caused by the structure of both the eye and brain and how they work together. Because of the anatomical make up of the eye and the complexity of the way images of transmitted from the eye to the brain, optical illusions are not as rare as one might

    • Long Distance Wireless Power Transmission

      Long Distance Wireless Power Transmission

      Simple wireless power transmission works because of the principles of magnetic resonance and magnetic induction. This power transmission system relies on two coils in range with each other and resonating at the same frequency. The coils need to be in range because the magnetic field of the source must be strong enough for the receiving

    • Transmission Electron Microscope

      Transmission Electron Microscope

      The transmission electron microscope (TEM) is a scientific instrument that uses electrons instead of light to scrutinize objects at very fine resolutions. They were developed in the 1930s when scientists realized that electrons can be used instead of light to "magnify" objects or specimens under study. TEMs provided a means to go beyond the magnification

    • What is Acesulfame Potassium?

      What is Acesulfame Potassium?

      Acesulfame potassium (Acesulfame K or Ace K, where “K” is the elemental symbol for potassium) is commonly used as an artificial sweetener or flavor enhancer. It is used in low calorie food products as it replaces sugar and other natural sweeteners that commonly add large amounts of calories. Acesulfame potassium’s trade names include “Sunett” and

    • How is Chemical Energy Used

      How is Chemical Energy Used

      There are many different kinds of energy but the single most widely used in society as well as in nature is chemical energy. Chemical energy allows energy to be stored for later use and it is also easy to access. Without chemical energy, many of the luxuries and even basic necessities that people have grown
