  • A demonstration electric motor.  This motor works on the principles of electromagnetism. Electric current running through the coil a magnetic field that opposes the bar magnets and causes the central shaft to rotate.  This converts electrical energy into rotary mechanical motion. .

  • An electrophotography discharge image of a ginko leaf (Ginkgo biloba ).  Also called Kirlian Photography, this technique shows the electrical discharge around an object. The principle of electrography is based on the corona discharge phenomenon that takes place when an electrically grounded object generates an electrical field, discharging sparks between itself and an electrode.

  • This image of an electrical discharge was made by placing a block of Lucite in the 6 megavolt (6Mv) electron beam of a linear accelerator. The Lucite gained a tremendous electrical charge when a grounded electrode was placed near it. The current flowing to ground melted the Lucite, leaving a record of the current flow. This fern-like fractal structure is quite common in electricity.

  • An electrophotography discharge image of an U.S. half dollar coin. Also called Kirlian Photography, this technique shows the electrical discharge around a metal object. The principle of electrography is based on the corona discharge phenomenon that takes place when an electrically grounded object generates an electrical field, discharging sparks between itself and an electrode.

  • A voltaic pile battery.  This type of battery was the first chemical battery and was invented by Alessandro Volta in 1791.  This battery consists of two different metals.  Here copper United States pennies manufactured before 1982 were used and the source of Zinc was zinc coated washers.  Cotton paper is placed between the coins and wetted with an acid.  In this experiment the acid used was 5% acetic acid from household vinegar. The vinegar is the electrolyte<br />
Unlike the Leyden jar, the voltaic pile produces a continuous electricity and stable current. The order of the stack is copper, zinc and then paper.  This pattern is repeated throughout the battery.

  • Thermogram of an electrical substation.  The substation houses a number of transformers that convert line voltage into the correct voltage for homes to use. The different colors represent different temperatures on the object. The lightest colors are the hottest temperatures, while the darker colors represent a cooler temperature.  Thermography uses special cameras that can detect light in the far-infrared range of the electromagnetic spectrum (900?14,000 nanometers or 0.9?14 µm) and creates an  image of the objects temperature..

  • An electrical spark created when a sheet pf photographic film is placed between two high voltage electrodes. Initially, the film builds up a charge on the surface and acts like as a capacitor. At a certain potential voltage the film, which is a dielectric material, breaks down and allows electrons to flow. The flowing electrons superheat the air resulting in an electrical spark which is recorded in the film emulsion. These are often called Lichtenberg Figures after the German physicist Georg Christoph Lichtenberg, who originally discovered and studied them.

  • An electrical spark created when a sheet pf photographic film is placed between two high voltage electrodes. Initially, the film builds up a charge on the surface and acts like as a capacitor. At a certain potential voltage the film, which is a dielectric material, breaks down and allows electrons to flow. The flowing electrons superheat the air resulting in an electrical spark which is recorded in the film emulsion. These are often called Lichtenberg Figures after the German physicist Georg Christoph Lichtenberg, who originally discovered and studied them.

  • The inside of a magnetron removed from a microwave oven.  The magnetron is a device that creates microwave radiation. A magnetron consists of an electron tube surrounded by a magnet. As electrons are released from the heated cathode they are forced to take a spiral path to the anode by the magnetic field, creating microwaves. This magnetron creates a microwave radiation that is the same frequency as a water molecule vibrates.  When water is exposed to just the right frequency, the water molecules will gain kinetic energy and become hotter.

  • A car spark plug firing.  The spark plug is the trigger that causes the gasoline to burn at a specific time in the cars internal combustion engine.  The spark plug fires and give the gas/air mixture the activation energy to start to burn.  This is a critical component in the thermodynamic cycle of an internal combustion engine.  A dirty or poorly adjusted spark plug will cause an engine to mis-fire, or fail to run.

  • Thermogram of resistive heating of a wire.  The large amount of current going through the wire is responsible for heating up the wire. .  The different colors represent different temperatures on the object. The lightest colors are the hottest temperatures, while the darker colors represent a cooler temperature.  Thermography uses special cameras that can detect light in the far-infrared range of the electromagnetic spectrum (900?14,000 nanometers or 0.9?14 µm) and creates an  image of the objects temperature..

  • The electrostatic field lines around a point charge and a cylinder.   The electric fields are shown by placing the two charged objects in a pan filled with cooking oil and pepper flakes.  The pepper flakes align in the electric field and allow visualization of the field.  In this image the left point is charged to -30,000 volts while the right ring has a potential of + 30,000 volts.  This image is part of a series showing different charging conditions.  Of special importance is the lack of fields showing inside the cylinder.  This is the classic case of no electrical fields inside an electrical conductor.  In this image the cylinder acts as a Faraday cage and shields the enclosed area from any external electrical fields..
