generators create electrical energy by creating a changing magnetic field. This works by moving a copper coil in a permanent magnetic field. The induced field created in the copper coil opposes the permanent one (according to Lenz's Law). These two opposing magnetic fields create the force that resists the rotation of the coils. When the light bulb is taken out no current can flow through the coil (Faraday's Law) so no opposing magnetic field is created. Hot Plate Why didn’t the power you…

are two field magnets on each side coil with wire. These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets, because when the current flow though iron that coil with wire, it will produce a strong electromagnetic field.…

Malcolm X once said, “There is no better than adversity. Every defeat, every heartbreak, every loss, contains its own seed, its own lesson on how to improve your performance the next time.” Loung Ung is a victim of the 1975 Cambodian Genocide and lost almost everything that she held dear to her including her home, her parents, and two of her sisters. However, she did not let their deaths weight her down as she went on to survive the wrath of the Khmer Rouge. The Khmer Rouge started a takeover…

Try being forced to move away from your home country, family, and everything you know to escape an unsafe environment. About 1.7 Million out of 7-8 million Cambodians were killed due to the Khmer Rouge Genocide, not one person has been persecuted for their actions during this time. Loung Ung was forced to leave everything she knew in Cambodia including her sister Chou, to move to America. She moved with Meng and Eang, Meng is Loung’s oldest brother and Eang is his wife. She moved because of the…

A cool, cloudy, but dry night rolls over the friendly confines northern Chicago. Two rabid packs of fans starved, and now frothing at the mouth as the taste for his or her team to finally take the title back home becomes more of a reality every night. With either outcome a drought will be ended, and a flood of emotion will consume the nation. It was Game 5 of the 2016 World Series and there can only be one! Which team will ultimately break the curse? Will the Indians be able to hold onto…

Magnetic therapy or magnet healing is a type of alternative medicine that have magnetic fields that generates healing powers towards a large number of diseases or conditions. These electromagnetic fields have been demonstrated to treat slow-healing fractures in the body and have shown good results towards to a few conditions. The website that has claimed to use this magnetic therapy are Skepdic.com. The claim that this complementary and alternative medicine practitioner is making goes…

Like ping pong and pool, air hockey is a fun, table-based game that incorporates hand-eye coordination with strategy to win. A typical air hockey table is about 4'x6' in size. The game surface of the table is perforated with hundreds of tiny holes. These holes allow air to flow through them and puck to glide smoothly. The playing field can be covered with blue and red lines similar to those seen in ice hockey. When you begin playing, you pick one player as the server. The player serves the…

players on the ice at the time, 5-center ice and one goal tender. In ice hockey the arena is much less crowded, and a less variety of skills than in footy. However due to the fact that the game takes place on ice there is much more skill and dexterity on ice that requires much more training. However, the actions done in hockey are quite repetitive, only navigating, passing, and shooting a puck with a hockey stick. However ice hockey seems to breed much more aggression than with footy. Players…

city of Birmingham, Alabama. A professional sports team could boost the city’s tourism substantially and possibly grow its population. The team would need to be from one of the country’s 5 biggest sports: Football, Baseball, Basketball, Soccer, or Hockey. There are reasons why Birmingham never had a professional sports team. The State of Alabama has always been dominated by the two college sports programs, Alabama and Auburn. These two college’s sports programs alone have the same amount of…

The history of hockey is one of the most contested among all sports. Traditionally, the birthplace of hockey is considered to be Montreal (Canada) (although more recent studies indicate the primacy of Kingston, Ontario or Windsor, Nova Scotia). However, some Dutch paintings of the 16th century depict a lot of people playing on a frozen canal in a game similar to hockey. But, despite this, Canada is still the birthplace of modern hockey. When in 1763 the Great Britain won the victory over Canada…
