CATEGORY 1

Strongest winds: Gales, 90 - 125km/h

Negligible house damage. Damage to some crops, trees and caravans. Boats may drag moorings.

CATEGORY 2

Strongest winds: Destructive, 125 - 164km/h

Minor house damage. Significant damage to signs, trees and caravans. Heavy damage to some crops. Risk of power failure. Small boats may break moorings.

CATEGORY 3

Strongest winds: Very destuctive, 165 - 224km/h

Some roof and structural damage. Some caravans destroyed. Power failures likely.

CATEGORY 4

Strongest winds: Very destuctive, 225 - 279km/h

Significant roofing loss and structural damage. Many caravans destroyed and blown away. Dangerous airborne debris. Widespread power failures.

CATEGORY 5

Strongest winds: Very destuctive, more than 290km/h

Extremely dangerous with widespread destruction.

However, wind is not always the most destructive aspect of a storm. A cyclone can cause massives walls of water – storm surges – to move to shore at a high speed. The force of the water can cause damage to properties near the coast and is likely accompanied by torrential rain.

Tropical Cyclones are characterised by strong continuous winds of more than 63 km/h. Once those winds reach 118 km/h the cyclone is classified as severe.  Australia's Bureau of Meteorology classifies cyclones by the following criteria:

Here the strongest winds and greatest rainfall are found.The eye is usually 40km in diameter, but can range in size from less than 10km to over 100km – as is the case with Yasi – depending on the size of the cyclone itself.

The heat energy combined with the rotation of the Earth, gets the cyclone spinning and propels it forward. While the cyclone looks savage from the outside, its low-pressure centre, commonly known as the eye, is deceptively calm. This belies the danger of the dense wall of cloud that surrounds it, which is the deadliest part of a cyclone.

TROPICAL CYCLONES ARE intense, spinning storm systems, with low-pressure centres that can be vast in size. They form over warm oceans and can wreak havoc when they approach the shore.

Did it work?= I didn’t work. I don’t think it worked because the moving magnetic current made by the electromagnet wasn’t
Strong enough and the opposing diamagnetic field made by the water want strong enough.
What would I change?= I would change my question. I think that my question was hard to measure for you could not be certain if the magnetic field created by each object would be strong or efficient enough
Was it accurate?= yes. I didn’t really think it would work and I had my doubts. And it didn’t need up working. So I think it was accurate according to my thoughts.

An electromagnet transfers electricity into magnetic force. Salt water conducts electricity better than normal water. Salt also weakens waters diamagnetism.

The experiment didn’t work but the electromagnet did. The electromagnet didn’t affect the sea water or salt water.

The further the electromagnet is away from the salt/sea water, will affect how much turbulence is generated from its moving magnetic force.

Paramagnetism: Paramagnetism,, kind of magnetism characteristic of materials weakly attracted by a strong magnet, named and extensively investigated by the British scientist Michael Faraday beginning in 1845. Most elements and some compounds are paramagnetic. Strong paramagnetism (not to be confused with the

Diamagnetism , kind of characteristic of materials that line up at right angles to a nonuniform magnetic field and that partly expel from their interior the magnetic field in which they are placed. First observed by S.J. Brugmans (1778) in and , diamagnetism was named and studied by Michael Faraday (beginning in 1845). He and subsequent experimenters found that some elements and most compounds exhibit this "negative" magnetism. Indeed, all substances are diamagnetic: the strong external magnetic field speeds up or slows down the electrons orbiting in atoms in such a way as to oppose the action of the external field in accordance with .

The diamagnetism of some materials, however, is masked either by a weak magnetic attraction ( paramagnetism ) or a very strong attraction ( ferromagnetism ). Diamagnetism is observable in substances with symmetric electronic structure (as ionic crystals and rare gases) and no permanent moment. Diamagnetism is not affected by changes in temperature. For diamagnetic materials the value of the susceptibility (a measure of the relative amount of induced magnetism) is always negative and typically near negative one-millionth.
