Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Answer: What are a few examples of non-contact force?

Triumph and Disaster: The 20th century saw a stupendous release of energies that had been pent up for the 250 years of Tokugawa isolation. By 1930 raw-material production had tripled the figure of 1900, manufactured goods had increased twelve-fold, and heavy industry was galloping towards maturity. Britain led the World War I Ailies in large orders for munitions, while Japan expanded sales of manufactured goods to Asian and other markets cut off from their usual European suppliers. Merchant shipping doubled in size and increased its income ten-fold as the European fleets were destroyed. Setbacks in the 1930s caused by the European postwar slump were only a spur to redouble efforts by diversifying heavy industry into the machine-making, metallurgical, and chemical sectors. Even the terrible 1923 Tokyo earthquake, which cost over 100,000 lives and billions of dollars, provided another stimulus due to the construction boom that followed. Riding the crest of this economic upsurge were the zaibatsu conglomeratesa dozen family-run combines, each involved in mining, manufacturing, marketing, shipping, and banking. These tightly controlled commercial pyramids were the true heirs to the old feudal structures. Japan's progress toward parliamentary democracy was halted in the 1930s by the growing nationalism being imposed on government by the generals and admirals. They proclaimed Japan's mission to bring progress to its backward Asian neighbors in language not so very different from that of the Europeans in Africa or the US in Latin America. After the Russian Revolution of 1917, the Soviet Union was regarded as a major threat to Japan's security, and the army felt it needed Manchuria and whatever other Chinese territory it could control as a buffer against Russian advances. In 1931 the Japanese occupied Manchuria. And then in 1937, with the popular support of ultra-right-wing groups, the army overrode parliamentary resistance in Tokyo and went to war against the Chinese Nationalists. By 1938, they held Nanking, Hankow, and Canton. Japanese expansionist policies were leading to direct confrontation with the West. Japan hoped that war in Europe would divert the Soviet Union from interference in East Asia, giving Japan a free hand both in China and, through its alliance with Germany, in French IndoChina after the defeat of France. The US responded to the Japanese invasion of IndoChina with a trade and fuel embargo, cutting off 90 percent of Japan's supplies. The result was the attack on the American fleet at Pearl Harbor (7 December 1941) and total war.

Among the early blows struck for independence was a rebellion in the town of Olhao. On 16 June 1808, the townsfolkarmed with little more than ancient swords, spears, and stonesattacked and captured the local French garrison. It's said that a party of local men then set sail from Olhao all the way to Brazil, without maps or navigational aids, to tell the king of the insurrection. The real battle, however, was waged under the leadership of the Duke of Wellington, whose coalition forces expelled the French after two years of bitter fighting. The war left Portugal further weakened, and in 1822 its major empire outpost, Brazil, declared independence. At the same time, a dispute over the crown continually raged between Pedro IV, the absentee monarch who preferred to reign as Emperor of Brazil rather than return to Portugal, and his brother Miguel. The power struggle, with strong overtones of absolutism versus liberalism, excited the interest and intervention of other powers. With British help, Pedro defeated Miguel off Cape St. Vincent in 1833, and his expeditionary force marched to Lisbon. Pedro took the throne, though armed struggle continued for months and the lingering bitterness long after that. By 1892 Portugal, racked by wars and the continuing expense of maintaining its African colonies (including those of Mozambique and Angola), declared itself bankrupt. The seeds of discontent with absolutist rule were sown. Kingdom's End Bloodshed would haunt the remaining years of the Portuguese monarchy. On 1 February 1908, the royal family was riding in an open carriage along the Lisbon river front plaza, Terreiro do Paco, when an assassin opened fire and killed King Carlos and the heir to the throne, Prince Luis Filipe. The prince's younger brother, Prince Manuel, was also hit, but he survived and was thus propelled to the throne at the tender age of 19. Amid republican agitation, a surprise uprising led by elements within the armed forces deposed Manuel in 1910. Having ruled for less than three years, Manuel died in exile in 1932 in England. The sudden end of more than seven centuries of monarchy brought confusion and crisis to the country. Presidents and prime ministers were ushered into and out of office an unbelievable 45 times between 1910 and 1926, until a military revolution suspended Portugal's problematic democracy.
