CMS MAGNETICS 4" x 6" Green Magnetic Viewing Film, See Magnetic Field with This Magic Film to Learn Magnetism. Applicable for All Kinds of Magnets Including Neodymium Magnets, Lots of Fun!

This same film is used by professionals, like engineers, developers and researchers to find out the magnetic field distribution when a group of magnets are involved. It is also used in the fabrication industry to image the internal defect of a steel part combined with an X-Ray machine. Encased within the green film are millions of nano size magnet particles which can turn freely when close to a steel object or a permanent magnet. When the magnet particles change their orientations, the reflection rate to the light will also change so to show the magnetic field beneath it. This is why the film will change shades when a magnetic field is applied. The film turns darker when the magnetic field lines are perpendicular to the surface, and lighter when the field lines are horizontal, i.e., across the surface. If one pole is placed under it, it will show the magnet as a dark area with a lighter outline. If both poles are placed under the film, the areas close to the two poles are dark but the border of the two poles will show up as light line, so you can tell the pole orientations. Our pictures show the two same dimension magnets but magnetized differently. Also the film is highly flexible and can be easily wrapped around magnetic assemblies. Tips and uses: 1. Place the film close to the magnet to observe the pattern changes so you can identify how the magnet is magnetized and where the magnetic poles are on the magnet. 2. The stronger the magnets, the better the results. We recommend neodymium magnets instead of ceramic magnets. 3. To get the same results of our pictures, be sure to use the same type and same quantities of magnets. 4. The film will not identify north or south poles. Should you need a pole identifier, you can check out our pole detector listings. 5. Do not fold the film since it will leave a permanent wrinkle on it.

ElectroSensor Electro Magnetic Field Detector

ElectroSensor Electro Magnetic Field Detector

ElectroSensor is a simple, accurate, affordable hand-held Gauss meter that measures Electro Magnetic Fields (EMF) with the push of a button. Weighing 2.5 ounces, and 4 inches long and three quarters of an inch wide, this EMF detector is light and compact; fits in your pocket, toolbox, or hand so you can always be prepared. The ElectroSensor is a value that offers fast, reliable, user-friendly measurements of electromagnetic pollution. It is efficient, accurate, portable, and easy to read in any light conditions with a colorful high visibility 10 LED 1.3-30milliGauss display range. Ready to use, AAA battery included. Sample the Electromagnetic field from 50-60Hz power, which most homes and businesses use, with the precise accuracy of 3dB over full range calibration traceable to NBS standards. As man-made alternating current (AC) is different than naturally occurring EMF prolonged exposure as low as 2milliGauss may be harmful. Once EMF sources are identified, you can moderate distance and exposure. The ElectroSensor can help assess EMF hot-spots in home and office. Perfect for concerns of Electrical Hypersensitivity Syndrome (EHS). The pick-up coil in the tip of the unit can be rotated for increased direction to pinpoint and measure EMF pollution in your environment such as TVs, computers, cell phones, dimmer switches, strong analog RF transmitters, and other electronic equipment. Accurately gauge potentially hazardous sources of emitted EMFs in seconds for electrical appliances and equipment such as microwave ovens, hairdryers, electric blankets, and florescent lighting. Be aware of potential risks so you can make an informed decision regarding your safety. TV Ghost Hunters and Paranormal Investigators use EMF meters to detect fluctuation frequently found at alleged haunted locations. Read the bright LED (light emitting diode) display even in the darkest of rooms and the silent device is perfect to use when recording potential EVP (Electronic Voice Phenomenon).
