      How Do Xenon Lights Work?

      Xenon is a noble gas–found all the way to the right on the periodic table of elements–that is odorless, colorless and heavy. It has many different uses, but one of the biggest uses that it has is the use in light bulbs. The reason for this is because when xenon is excited, it gives off

    • Harmonic Balancer

      Harmonic Balancer

      A harmonic balancer is a device that is connected to an engine’s crankshaft in order to reduce any vibration’s negative impact on the crankshaft and to dissipate the energy that shaft rotation creates. Since the device is the engine compartment’s first element that is connected to the shaft, it absorbs the majority of the energy

    • What Are Permanent Magnets?

      What Are Permanent Magnets?

      A permanent magnet (ferromagnet) is a material that produces a magnetic field. Permanent magnets are made from ferromagnetic materials, such as iron, and are created when the material is placed inside of a magnetic field. When the magnetic field is removed, the object remains magnetized. Permanent magnets have a permanent magnetic field and do not

    • Pulse Induction Metal Detectors

      Pulse Induction Metal Detectors

      Metal detector technology has been used for a number of decades to locate various metallic artifacts and precious metallic ores. An uncommon, but accurate metal detector is the Pulse Induction Metal Detector. It uses Pulse Induction Technology to find metals. What is Pulse Induction Technology? In Pulse Induction technology, a coil is used as a

    • Total Harmonic Distortion

      Total Harmonic Distortion

      Total Harmonic Distortion (THD) is a measured difference in audio levels between the input audio signal’s harmonics and the harmonics of the output audio signal of an amplifier or other audio device. Output Distortion Level As the signal passes through an amplifier it is always somewhat distorted at its output. The waveform at the input

    • How Does Sound Travel?

      How Does Sound Travel?

      Sound is characterised as a series of waves that move through a particular medium. A medium is some sort of a subtance–whether it be water, plasma, air, a solid, or anything else–that these waves move through. The waves cause the particles in this substance to vibrate which is how the sound is potentially heard. A

    • Eddy Currents

      Eddy Currents

      Eddy currents are also referred to as Foucault currents and are created when conductors are exposed to a changing magnetic field because of a field source’s relative motion. Their applications include induction heating and non-destructive testing. Eddy currents are continually researched in order to develop new applications. How do Eddy Currents Work? Eddy currents are

    • How Does an Ultrasonic Nebulizer Work?

      How Does an Ultrasonic Nebulizer Work?

      An ultrasonic nebulizer is a small, portable device that uses ultrasonic sound waves to break liquid particles down into a fog so that they can be inhaled easily. Patients who have asthma, COPD, pneumonia, chronic bronchitis, emphysema, or other chronic conditions, most often use them for medicinal purposes. While other devices can deliver the medicine

    • Vibration Isolators

      Vibration Isolators

      There are a number of vibration sources throughout the world. In most cases, these movements have undesirable effects on things used in daily life, such as buildings and vehicles. Vibration isolators reduce or eliminate the effects of vibrations on equipment and structures. These devices are commonly referred to as shock mounts, snubbers, machine mounts, and

    • What is Magnetic Wire?

      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
