back and forth‚ and the attached coil moves along with it. Additionally‚ magnet is attached with coils on a cardboard. When the coil alternately approaches and move back from the magnet‚ the flux through the coil changes. As a result of this‚ an ac emf is induced in the coil. Next‚ this electrical signal is sent to an amplifier and to the speakers respectively. In a moving-magnet microphone‚ the magnet is attached to the diaphragm and moves relative to a stationary coil. The handmade microphone did

on each coil and one-half the circular-mil area of wire. In other words‚ if forty turns of No. 17 wire were used on the original motor‚ eighty turns of No. 20 should be used on the new motor. RECONNECTING THE POLYPHASE MOTOR FOR CHANGE IN SPEED It has been mentioned that the speed of a three-phase motor decreases if the number of poles is increased and vice versa. (A change in speed is also caused by a change in line frequency.) Most methods of changing speed involve rewinding the coils and altering

‘The Dangers of Dengue Fever and How to Keep You Compound Dengue Free’. Dengue is the most common viral illness around the world caused by a small mosquito. Regrettably‚ it can lead to serious medical problems like dengue. To make the picture clearer‚ dengue fever is not caused by every mosquito. In fact‚ it is caused by the Aedes aegypti mosquito which carries a deadly virus. An infected person might have a high chance of developing high fever‚ rashes‚ feel nausea and experience muscle and joint

including humans. This is a tropical disease caused by a parasitic round worms known as microfilariae that enter the blood. Genus involved include Wolbachia‚ Wuchereria and Brugia. For humans to get this disease they must usually get bitten by a mosquito‚ which acts as the host and vector for three species Wuchereria a bancrofti (most common 90%)‚ B timori‚ and Brugia malayi. History This disease has been documented in ancient text by Ancient Greek and Roman scholars. They noted the similarities

Fever Dengue fever‚ a very old disease‚ has reemerged in the past 20 years with an expanded geographic distribution of both the viruses and the mosquito vectors‚ increased epidemic activity‚ the development of hyperendemicity (the co circulation of multiple serotypes)‚ and the emergence of dengue hemorrhagic fever in new geographic regions. In 1998 this mosquito-borne disease is the most important tropical infectious disease after malaria‚ with an estimated 100 million cases of dengue fever‚ 500‚000

What is Malaria? (Knowing more on how to deal with Malaria) A. History of Malaria Although the parasite responsible for P. falciparum malaria has been in existence for 50‚000–100‚000 years‚ the population size of the parasite did not increase until about 10‚000 years ago‚ concurrently with advances in agriculture and the development of human settlements. Close relatives of the human malaria parasites remain common in chimpanzees. Some evidence suggests that the P. falciparum malaria may have originated
