forces between superconducting magnets on board the vehicle and coils on the ground. The following is a general explanation of the principle of Maglev. fig. 1.1 1.1.1 Magnetic Levitation The "8" figured levitation coils are installed on the sidewalls of the guideway. When the on-board superconducting magnets pass at a high speed about several centimeters below the center of these coils‚ an electric current is induced within the coils‚ which then act as electromagnets temporarily. As a result‚ there

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"

Heating effect of electric current are below (i) Electric iron: In an iron the upper part is grooved. In this groove a coil is placed. Mica as an insulator is placed between the metal part and the coil‚ so that there is no electrical connection between them. Mica is a bad conductor of electricity but it is a good conductor of heat. Due to the flow of current through the coil it becomes heated and the heat transferred to the metal part through mica. Finally the metal part becomes heated. Iron is

towards the condensor. Damage can occur‚ and the accululation of dust will result in poor performance‚ and the need for cleaning of the outdoor condensing coil. Refrigerant Leak A refrigerant leak is not a repair that the average homeowner can provide. Leaking refrigerant can result in a frozen coil‚ and the AC blowing warm air. When the coil has a frosted or iced appearance‚ it is a likely indication of low refrigerant. The leak will require repair before recharging with refrigerant‚ otherwise

constant B field can be detected by a small compass. If the current in the wire is time-varying‚ the B field that exists will also be time-varying. This time-varying B field can be detected by the electric field that it induces in a small inductor coil placed near the wire. In this laboratory‚ measurements on an apparatus with a long straight current-carrying wire will be used to accomplish the following objectives: 1.1 Determination of the direction of the B field surrounding a long straight
