1. Tesla Coil
Coal is one of the many energy sources that exists in our world today. Coal, along with oil and gas are known as "fossil fuels". They produce 66% of the world's electrical power, and 95% of the world's total energy demands, which includes heating, transportation, electricity generation and other uses (Darvill). What exactly is coal you ask? Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material, formed from compaction and indurations of variously altered plant remains similar to those in peat. Peat is an unconsolidated deposit of plant remains from a water-saturated environment such as a bog or mire; structures of the vegetal matter can be seen, and, when dried, peat burns freely (Coal Information). .
These days coal is not as visible as it was back a century ago when it was used to power railroads, boats and fuel factories that produced products used to manufacture the world. Even though it is not as visible, it is still being used throughout the economy. Actually, we use more coal today then in any other time in our nation's history. Coal generates 56% of the electricity consumed in America each day, which is way more than any other energy source (Coal Today). Nine out of Ten tons of coal mined in the United States today is used to generate electricity. Worldwide coal provides 40% of electricity generated. Manufacturing plants and industries use coal to make chemicals, cement, paper, ceramics, and metal products. Coal gas is also used to make methane and ethylene, which can be used to make plastics, medicines, fertilizers, and tar (Coal"s Past). .
Coal has many advantages. One of them being that it is plentiful. There is enough .

coal around for it to last the next 300 years at the rate we are using it now. Therefore coal has a good future being that it will be around for a long time and will have the potential for growth. It is also very cost effective.
Though spring can be in many shapes, our choice will be coil spring. ... Coiling Hot winding. ... The steel is coiled around a mandrel while red hot. ... Quenching Then, the coiled metal it is immediately removed from the coiling machine and plunged into oil to cool it quickly and harden it. ... Type of spring A coil spring will be created with resemblance of the diagram above. ...
The second theory that the number of coils will affect the magnetic field strength will be tested by repeating the experiment, however increasing the number of coils each time, whilst leaving the current constant at 1A. A graph of number of coils versus tan ∂ will show the relationship between the two. ... It was repeated for 7, 9, 11, and 13 coils of wire. ... Magnetic field strength of earth = Magnetic field strength of coils. ... At 13 coils B = ∏ x 2.0x10-7 x 1.0 13 0.12 = 6.8067 x 10-5 nT At 11 coils B = ∏ x 2.0x10-7 x 1.0 11 ...
I also think that the more you wrap the nail with the coil the electromagnet would get stronger. ... Wrap the coil of insulated wire to the U shaped metal (about 10 or more times) 5. Use the crocodile clips to clip on the ends of the coil of insulated wire 6. ... In the middle of the process we had to change some of our equipment like the wires, coil and the battery. ... If I could do this experiment again I would be more patient and work on wrapping to coil slowly and more tightly....
There are four main factors that affect the strength and size of this field: Current/voltage Number of coils Size and shape of core Material of core (iron being the strongest) For example: two coils wrapped around the iron core would induce twice the strength of one coil. By this I mean that each coil will have twice the strength of one coil on it's own. Below shows a single coil's magnetic field. ... We will also be testing the strength when the amount of coils are increased or decreased. ... If the coils are coiled towards end, then one end will be more powerful than the othe...
Hydroelectric power is the method in which electricity is generated by water. the energy developed by water when dropped by incredible force is used to move the turbine which is attached to the generator .a way of generating electricity - if energy(any sort of energy- in this case the force of the water) is applied to a magnet in the coil then electricity is generated. the opposite of this phenomenon takes place in a fan where electricity is generated in the coil which forces the magnet to rotate (as when electricity flows through a coil then a magnetic field is formed around it and as both th...
In the slick, tiled hallway, the snake arranges itself into s-shaped coils and attempts to move, though rather slowly, across the floor. ... In this form of motion, the coils of the snake's body push horizontally against the ground in a backward and diagonal direction. ... The snake, placed between the two boards coiled its body against the boards in order to push off and push itself forward. This constituted concertina motion, where the snake locked its back coil against the board and pushed forward. In this type of motion, the snake's posterior coils press outward against the b...
The coil is then inserted into the tubing and the solvent is evaporated. The tubing shrinks on to the coil as the solvent evaporates resulting in a very tight fit between the coil and tube. This tight fit can yield direct transfer of stress from the coil to the polymer. ...
In a speaker there are a few main parts including a cone, a voice coil, and a permanent magnet. The ends of the voice coil are connected to the back of a panel receiver or stereo and the receiver sends a signal through the voice coil which interacts with the magnetic field of the magnet which produces an alternating force that pushes and pulls on the cone. ... In a recording device, a weak electrical signal from a microphone is routed to an amplifier where it is amplified and then sent to the recording head which is essentially a coil wrapped around a piece of iron in the shape of a horsesho...
