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. Safety Considerations IMPORTANT! What is attracted to magnets? Electromagnets What is an electromagnet? Who else has cool stuff on magnets?
AQA – GCSE Additional Science GCSE Additional Science offers students a broad, coherent course of study that adds to their knowledge and understanding of the living, material and physical worlds. For Key Stage 4 (KS4) learners it is a good follow on from GCSE Science A or B. The three core Sciences of Biology, Chemistry and Physics are taught separately using Unit 2 modules from the individual subject GCSEs. This allows for co-teaching with the relevant Science GCSEs. This specification allows subject specialists to teach the appropriate units focussing on their area of expertise, or it can be taught by an integrated Science teacher. Teachers can choose between two routes: three separate exams in Biology, Chemistry and Physics together with a controlled assessment, ortwo combined exams plus the controlled assessment. It is suitable for students of all abilities and helps students to understand theoretical concepts alongside developing practical science skills. Specification Amended due to Changes to GCSEs.
Basic Electromagnetic Wave Properties - Java Tutorial 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. An electromagnetic wave moves or propagates in a direction that is at right angles to the vibrations of both the electric and magnetic oscillating field vectors, carrying energy from its radiation source to undetermined final destination. ν = c/λ Contributing Authors Matthew Parry-Hill, Robert T.

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.. Click HERE for some additional information on batteries and what we're doing to them. These are some of my projects have I found to be enlightening to me in the learning process. How it works: (or click HERE for my explanation of how the Bedini works) When dealing with an electric motor/generator we generally use the same basic principles.. By capturing these high voltage spikes created in the switching process, we can send them to another battery and charge it.
GCSE PHYSICS - Electromagnetism - How does a Residual Current Circuit Breaker Work? - RCCB Electromagnetism Residual Current Circuit Breaker - RCCB. An RCCB is also called an RCD (Residual Current Device). How does a Residual Current Circuit Breaker Work? This type of circuit breaker works by comparing the current going in to an appliance with the current coming out. When an appliance is working correctlyall of the current entering the appliance through the live wire is returned to the power supply through the neutral wire. If something goes wrong with the appliance some of the electric current will flow through the earth wire. The coil connected to the neutral wire now has aweakermagnetic field than the coil connected to the live wire. The RCCB acts to switch off the electricity much faster than a fuse or MCB.

GCSE PHYSICS - How does a Circuit Breaker Work? - What is an MCB? - Electromagnetism Electromagnetism How does a Circuit Breaker Work? This page describes a simple circuit breaker. The circuit breaker acts as a safety device in the same way as a fuse. 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.
