Sources The Model T, sold by the Ford Motor Company from to , was the earliest effort to make a car that most people could actually buy. The Model T was actually affordable and it became so popular at one point that a majority of Americans owned one, directly helping rural Americans become more connected with the rest of the country and leading to the numbered highway system. He successfully tested one on Christmas Eve, , with the help of his wife, Clara, taking a break from Christmas cooking. The engine worked for 30 seconds, long enough to confirm for Ford that he was on the right track.

The electronics sector produces electronic equipment for industries and consumer electronics products, such as mobile devices, televisions, and circuit boards.
The products produced by this sector are used in a variety of consumer and industrial electronics products. These industries are growing rapidly as a result of increasing demand from emerging market economies. As a result, many countries are increasingly producing more electronics. Investment in foreign production of electronics has increased dramatically and resulted in many new factories and factory expansions.
Electronics sector growth is greatly accelerated by increasing consumer spending around the world. As developing economies grow, consumer demand for electronics also increases. Countries that produce electronics now have strong consumer bases that can afford new electronic products.
Increased competition is driving the costs associated with electronics production down and expanding the availability of affordable electronics products. This increase likely means better profitability for the industry at large over this time. The supportive role of the electronics sector in providing equipment and components for other industries also supports a significant increase as consumers demand more automobiles, energy-efficient homes, and medical technologies. Many electronics brands are now offering their products at their own stores as a means of becoming more profitable.
Online stores, such as Amazon AMZN , also compete for customer spending and offer products not available in traditional stores. As the variety of electronics products increases, stores struggle to offer enough of the more popular products to consumers and concede some of the market to online retailers. Volatility in company valuations and stock values is increasingly becoming normal for electronics retailers as the industry matures and experiences changing pressures.
Changes resulting from store closures, mergers and acquisitions , and declining prices are pressuring the electronics sector to become more efficient and more profitable.
While purchasing volume increases, many larger companies are in a period of decline as the sector becomes fragmented with a greater number of companies offering electronic products. Compare Accounts.

People like Benjamin Franklin, who helped figure out the mystery of electricity back in the 18th century, believed it was a flow of positive charges, so it flowed from positive to negative. Now we have better ideas about how electricity works, we tend to talk about current as a flow of electrons, from negative to positive, in the opposite direction to the conventional current. How an electric motor works—in theory Photo: An electrician repairs an electric motor onboard an aircraft carrier. Suppose we bend our wire into a squarish, U-shaped loop so there are effectively two parallel wires running through the magnetic field. One of them takes the electric current away from us through the wire and the other one brings the current back again. In other words, when we switch on the electricity, one of the wires will move upward and the other will move downward.

Another equation used, that gives the magnetic field due to each small segment of current, is the Biot—Savart law. Computing the magnetic field and force exerted by ferromagnetic materials is difficult for two reasons. First, because the strength of the field varies from point to point in a complicated way, particularly outside the core and in air gaps, where fringing fields and leakage flux must be considered. Second, because the magnetic field B and force are nonlinear functions of the current, depending on the nonlinear relation between B and H for the particular core material used. For precise calculations, computer programs that can produce a model of the magnetic field using the finite element method are employed. Magnetic core[ edit ] The material of a magnetic core often made of iron or steel is composed of small regions called magnetic domains that act like tiny magnets see ferromagnetism.
