      Magnetic Propulsion

      Magnetic propulsion is the act of moving an object with magnetic fields and a flowing electrical current. The current is used to manipulate the system’s magnetic field or charge a fluid in the system that can be repelled. The Lorentz force then pushes the conductor in a direction that is perpendicular to the magnetic field

    • 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

    • What is the Fifth State of Matter?

      What is the Fifth State of Matter?

      The fifth state of matter is actually the first phase of matter. It is called a Bose-Einstein Condensate. Matter in the fifth state is really slow moving and extremely condensed. It only exists at near absolute zero temperatures and is very fragile and unstable. It was discovered in 1995 by Eric Cornell and Carl Weiman through experimentation with rubidium,

    • Antigravity Propulsion

      Antigravity Propulsion

      True antigravity propulsion involves using a material or technological effect that counteracts the effects of gravity without using aerodynamic lift, electromagnetism, or some other balancing force. Likewise, antigravity does not refer to situations in which an object or person experiences lack of weight such as being in a pool, free fall, or high altitude orbit.

    • 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

    • What Are the Four Dimensions?

      What Are the Four Dimensions?

      The four dimensions are concepts in mathematics to describe different shapes. It is easy to understand a first dimension, second dimension and third dimension shape. All things are 3D in the world, but images can be 2D. A first dimension is as easy as a line. However, what is the fourth dimension? The fourth dimension

    • What is Transconductance?

      What is Transconductance?

      Transconductance is a property of some electronic components and is also known as mutual conductance. It is the opposite of resistance. The measure of transconductance is the ratio of the electrical current change at an output port as compared to the voltage change at the input port. The measure of transconductance is commonly used in

    • Magnetic Permeability

      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

    • What is a Peltier Cooler?

      What is a Peltier Cooler?

      A Peltier Cooler or Peltier Heat Pump is a type of refrigerator that has no moving parts and is capable of transferring heat to either side of itself. Peltier Coolers are advantageous as they are solid state devices and only require a DC electrical current in order to cool an object or area. A Peltier

    • Dielectric Constant

      Dielectric Constant

      A dielectric constant measures the extent that a material concentrates electrostatic flux and is also known as the relative static permittivity, static dielectric constant, and relative dielectric constant. It is essential when determining if a substance can be used in a capacitor or various chemistry and physics applications. A material’s dielectric constant value must be
