      What is Magnetic Wire?

      Magnetic wire is a copper or aluminum wire that produces an electromagnetic field when wrapped into a coil and connected to a power supply. It is used in a number of applications and is a vital component in many different devices. Magnetic wire can be used in electrical to electrical, electrical to mechanical, and mechanical

    • Infrared

      Infrared

      Infrared light is a form of electromagnetic waves. In its visible form, infrared can be seen as red or violet. Visible infrared waves are very short, measuring about 750 nm in length; longer infrared waves which are closest to microwaves are about 1mm in length. Infrared Waves While most infrared wave lengths give off heat,

    • 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

    • Petabyte

      Petabyte

      A petabyte is a measurement unit that describes a piece of information that is equal to 1,000 terabytes or one quadrillion bytes of data. A single petabyte is equal to 1,000,000,000,000,000 bytes . When a petabyte describes computer memory, it is also used in reference to a corresponding power of 1024. The approved scientific symbol

    • What is an Ultrasonic Pest Repeller?

      What is an Ultrasonic Pest Repeller?

      An Ultrasonic Pest Repeller is an electronic device that uses ultrasonic sound waves to repel insects, rodents, and other pests. Though humans are incapable of hearing these sounds, many animals, insects, and rodents can. There is much debate concerning the ultrasonic pest repeller’s ability to actually get rid of pests. While some people claim that

    • Hot Water Circulators

      Hot Water Circulators

      A hot water circulator (circulator pump) is a device that circulates hot water through a house’s pipes so that hot water is always instantly available. In traditional one-way plumbing systems, water is run through a hot water heater and directed through the pipes towards the taps whenever a tap is turned on. When a tap

    • Potassium Perchlorate

      Potassium Perchlorate

      Potassium Perchlorate (Potassium Chlorate (VII), perchloric acid, potassium salt, peroidin, and KClO4) is an inorganic salt that is used as a strong oxidizer. The function of potassium perchlorate’s oxidizer trait really depends on the chemical use. Potassium Perchlorate can be found in the following common items: Fireworks – Fireworks have many chemical compounds inside them,

    • How Do Quartz Watches Work?

      How Do Quartz Watches Work?

      A quartz watch is one that uses a tiny, paper thin piece of quartz to measure the time. An electrical pulse is sent into the quartz which causes it to vibrate. This vibrating is then picked up by the watch and it is measured. Then, the vibrating pulse is sent to the hand which turns

    • What is a Psychrometer?

      What is a Psychrometer?

      A psychrometer is a type of hygrometer and is used exclusively to determine the relative humidity or moisture content in the air. Psychrometers represent an older humidity measurement form and electronic sensors that depend on changes in electrical resistance and capacitance rather than condensation temperature have widely replaced them. However, psychrometers are still found in

    • What is a Hydraulic Excavator?

      What is a Hydraulic Excavator?

      A hydraulic excavator (digger) is a large vehicle that is designed for excavation and demolition purposes. Hydraulic excavators consist of a chassis, boom, and bucket, and move via tracks or wheels. They range in size and function, an example of which is the similar but smaller “mini excavator.” All versions are generally designed for the
