Over the next decade‚ the most vibrant Wireless Power Transmission (WPT) markets will involve the contactless charging of portable and mobile equipment‚ in particular consumer electronics and electric vehicles. Today‚ development teams worldwide are stretching the boundaries of physics using available components to create systems that are able to compete with the efficiencies of wired solutions while offering the conveniences of wire free connections.

tropics (Epstein‚ 2000). The virus has four antigenically related serotypes‚ which are named DEN-1‚ DEN-2‚ DEN-3‚ and DEN-4. Each dengue serotype is a variation of the flavivrus genus. Dengue is spread by the aedes aegypti‚ a domestic‚ day-biting mosquito that prefers to bite humans. Currently‚ there is no vaccine available to prevent dengue. Each type of the dengue virus is re-emerging worldwide‚ especially in the Western Hemisphere. Research has shown that several factors are contributing to

The particular heater shown here was designed for heating "getters" and electrodes in gas discharge lamp assemblies. The result is that the work coil is attached to the electronics box. It could easily be located in a "wand" at the end of a cable.I’m going to assume that you’ve read Richie’s page that covers the theory of induction heating and specifically

CHAPTER - 13 MAGNETIC EFFECTS OF ELECTRIC CURRENT 1) Magnetic field and Field lines:- a) Magnetic field :- The region around a magnet where the force of attraction or repulsion can be detected is called magnetic field. Magnetic field around a magnet can be detected by using a magnetic compass. b) Magnetic field lines:- Magnetic field lines are the paths around a magnet along which the north pole of a magnetic compass needle tends to move. The magnetic field lines around

This produces a field which is similar to that of a bar magnet. A coil of wire like this is often called a solenoid. http://www.bbc.co.uk/bitesize/standard/physics/using_electricity/movement_from_electricity/revision/1/slideshow-1/2/ An electromagnet consists of a coil of wine‚ through which a current can be

HSC Physics Space 1. The Earth has a gravitational field that exerts a force on objects both on it and around it Define weight as the force on an object due to a gravitational field Mass is a measure of the amount of matter in an object‚ it is measured in kilograms (kg). The weight of an object is a measure of the force with which it is attracted by a gravitational force‚ it is measured in Newtons (N). It is directly related to the strength of the gravitational field at a point where the object
