Introduction Did you know that you probably used an electric motor today? Yes‚ that’s right. If you put on clothes that were washed in a washing machine‚ rode in a car‚ ate food from a fridge‚ warmed up lunch in a microwave‚ or played a video game‚ you used an electric motor! Try this science fair project and you’ll learn how to make a simple electric motor by having two magnets "talk" to each other. As they interact‚ they will alternate between "liking" each other (being pulled together)‚ and "disliking"

Why You Should Choose Toroidal Transformers. Transformers are important and highly efficient devices that have incredible applications. Construction mostly distinguishes them and they serve the basic applications. There are different types of transformer applications‚ but toroidal transformer applications are the best. Here are some reasons why you should always use them. Easy to mount. Most toroidal transformer applications do not have very complex designs‚ so you will be able to install them easily

Procedure: 1. The compass was placed on the lab table with no magnets nearby to identify what direction was north relative to the classroom. 2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular

The Law of Navigation Law Number Four is called “The Law of Navigation.” The by-line for this chapter reads‚ “Anyone can steer the ship‚ but it takes a leader to chart the course.” That by-line reflects something that anyone can beat time‚ but not everyone is a conductor. Anyone can learn how to play a piano but not all will become a pianist. Everyone can learn to swing a golf club but not everyone can become a golfer. Regarding conducting‚ more than a few famous conductors have said that they can

Why is magnetic flux through closed surface zero while electric flux not? Gauss’ Law for Magnetism The net magnetic flux out of any closed surface is zero. This amounts to a statement about the sources of magnetic field. For a magnetic dipole‚ any closed surface the magnetic flux directed inward toward the south pole will equal the flux outward from the north pole. The net flux will always be zero for dipole sources. If there were a magnetic monopole source‚ this would give a non-zero area integral

Magnet status is now a big thing/idea in the healthcare industry. Although I work in a nursing home facility‚ the 14 forces of Magnetism give me an overview of how I could potentially enhance myself professionally. The forces of Magnetism sum up what healthcare facilities should do to provide optimal patient care. Of the 14 forces of Magnetism‚ I think that the five forces that I could incorporate into my practice are: quality of nursing leadership‚ personnel policies and programs‚ quality of care

Though very few remember him‚ Mesmer’s interpretation of animal magnetism marked the beginning of mental therapy as we understand it today. At a time when methods reminiscent of medieval superstitions were being viewed with suspicion. His theories bridged the gap between ancient superstitions and modern psychotherapy. Franz Anton Mesmer (1733-1815) was born on the 23rd of May 1733 at the village of Iznang near Switzerland‚ on the German side of Bodensee (Lake Constance). He was originally intended

IGCSE MAGNETISM AND ELECTROMAGNETISM DEFINITIONS AND CONCEPTS HARD AND SOFT MAGNETIC MATERIALS: Materials‚ which are difficult to magnetise and de-magnetise. Soft materials are easy to magnetise and de-magnetise. MAGNETIC FIELD: The area around a magnet where another magnet would feel a force. MAGNETIC FIELD LINES: Show the direction of the magnetic field. The lines run from North to South. Where the field is strong‚ they are close together. INDUCED MAGNETISM: A magnetic material can

The Facts in the case of Mr. Valdemar (Summary) Of course I shall not pretend to consider it any matter for wonder‚ that the extraordinary case of Mr. Valdemar has excited discussion. It would have been a miracle had it not -- especially under the circumstances. Through the desire of all parties concerned‚ to keep the affair from the public‚ at least for the present‚ or until we had farther opportunities for investigation -- through our endeavors to effect this -- a garbled or exaggerated account
