Fourteen Plates In The Earth's Crust
2,865 wordsThe Forever Moving Land The land below us is always in motion. Plate tectonics studies these restless effects to give us a better understanding of the Earth and its past. New molten rocks are poured out in the form of magma from the mid-ocean ridges. The rock is recycled and re-entered back into the earth in deep ocean trenches through convection current. The convection current in the mantle drives plates around either against or away from each other. These collisions give rise to earthquakes, v...

Time O The Paper Clips
822 wordsWhat Affects the Strength of an Electromagnet? Aim What is the effect of increasing the current and increasing the number of coils when picking up paper clips? Definition First of all, an electromagnet has to be defined. An electromagnet can also be called a Solenoid, Which consists of a core of iron and then wire is wrapped round it. Prediction I predict that as the current carried in the wire gets stronger, so will the magnetic field surrounding the electromagnet. Therefore, I think that the a...

High Voltage From The Ignition
1,996 wordsIgnition Systems: New and Old Jeff Tuttle Period 39/9/04 Ignitions systems in motor vehicles have evolved in the past thirty years. Points was a simple concept but was not reliable and needed adjustment and replacement of components seemed constant. Today a magnetic sensor relays a signal to the computer which in turn sends the voltage to the selected cylinder to ignite the fuel / air mixture. There are not mechanical parts to fail or become corroded and brittle. There are many different parts t...

High Altitude Emp Detonations
972 wordsElectromagnetic Pulse has been known of since the 1940's when nuclear weapons were being trialed and produced. Yet, due to the lack of sufficient data the exact effects of EMP were not fully known until 1962. During this time a series of tests were being conducted which were code named 'Fishbowl'. "An electromagnetic pulse consists of a broadband, high intensity, short duration burst of electromagnetic energy. If nuclear detonation occurs, the electromagnetic pulse consists of a continuous frequ...

High Magnetic Fields
462 wordsThe physics of high-temperature, multi-keV, collision less plasmas, usually immersed in a magnetic field of complex geometry, is dominated by the behavior of unique many-body systems in which collective phenomena dominate over rare two-body collisions. These plasmas are usually far from the thermodynamic equilibrium, due to sources of mode-excitation energy that owe their existence to factors including: electrodynamic forces with spatial inhomogeneities (this is the case in magnetic or inertial ...

Bermuda Triangle Mystery
2,229 wordsScience has an overwhelming way of trying to find a reason for anything and everything that occurs on, under and over the surface of the earth. If a thing cannot be explained by science then it is either dubbed as superstition or coincidence. One such mystery churned out after years of inhabiting this earth is the Bermuda triangle. For years, it has baffled scientists worldwide and evaded any logical explanation for its existence other than perhaps as a symbol of Nature's superiority over mankin...
