Magnet Man - Cool Experiments with Magnets. Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets.
Some of the experiments are very basic - things you've done since third grade. Others are unique - perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you. Also shown are several cool magnetic toys you can buy. Have fun with hands-on experiments! Rick Hoadley(For other cool toys and puzzles, check this out!) Last updated: 26 Feb 2017. . , that means that at the underlined link there is some kind of experiment you can buy or build which will help you learn about the world of magnetism.

Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity (or amplitude) and quantity of energy.
This interactive tutorial explores the relationship between frequency, wavelength, and energy, and enables the visitor to adjust the intensity of the radiation and to set the wave into motion. The tutorial initializes with a visible light wave appearing in the window having a wavelength of 650 nanometers (red light) and amplitude of 61 candelas. Energies associated with waves in the tutorial appear beneath the window and are given in units of kJ/mole. To adjust the wavelength (and simultaneously, the frequency) of the wave, translate either the Wavelength or Frequency sliders to the left or right.
The standard unit for all electromagnetic radiation is the magnitude of the wavelength (in a vacuum), which is usually reported in terms of nanometers for the visible light portion of the spectrum. Ν = c/λ. Magnetic field in a solenoid. Pulse Motors - Electromagnetic Energizing. Here are some of the motors I have worked on in my quest to discover what they call Overunity, and I have become thoroughly convinced of several ways in which it can be done.
However, even if we cant achieve some revolutionary breakthrough that has been hidden for years, we can still charge some damn batteries and save some money. You may not realize it but the batteries you throw away on a regular basis are still good for something. They dont have to be "rechargeable" to be recharged.. You can even recharge non-rechargeable batteries with a conventional charger, as long as you make sure they dont get too hot and explode (since they dont have those handy gas vents). The method we are using to charge these batteries is "Pulse Technology", using high voltage "transient" energy, meaning it is a fleeting pulse frequency we are giving and receiving rather than a constant flow of current over time. rather than flicking the switch on we are flicking it on and off over and over.

This page describes a simple circuit breaker. See thenext page for the residual current circuit breaker. The circuit breaker acts as a safety device in the same way as a fuse. Circuit breakers that are used at the distribution board in houses are called MCBs (minature circuit breakers). When the live wire carries the usual operating current, theelectromagnet is not strong enough to separate the contacts. After the fault is repaired, the contacts can bepushed back together bylifting a switch on the outside of the circuit breaker.
