One new technology that has affected people’s lives is the electric train .Electric trains have help us to get to our destination faster and more efficiently than any normal wasteful train.

Have you ever came home and wondered how do your light turns on and of or why do magnets repel the same poles? A physicist was the reason we have knowledge about electromagnetism today. The factor of this electromagnetic field was when he noticed that electrical fields and magnetic fields can couple together to form electromagnetic waves. Energy consumption has increased over the years because of electricity. In “A Dynamical Theory of the Electromagnetic Field” (1865) James Clerk Maxwell produced the first produce the first complete set of equations governing electricity and magnetism, expressed in terms of fields. The theory of electromagnetism from James Clerk Maxwell which led to the invention of the Electric Grid.

We first propose using thick copper as the material we chose for wire type. We propose using thick copper because, in the trials, the electromagnet with string wire could only hold 0 filings, the electromagnet with aluminum material could hold 31 filings and the electromagnet with a copper wire could hold 83 pieces of filing. The pattern shows

A magnetic energy generator is ideal for individuals seeking an inexpensive energy-efficient reliable type of constant energy. These products are employed in a way

The human race has advanced a great deal over the course of recent history, particularly so since the 18th century. Countless of these developments in society can be attributed to the achievements of engineers - however, despite this, many do not realise their contribution and importance. One of the fundamental bases behind these engineering feats is the harnessing of energy sources, such as electrical and heat energy. This has allowed for many innovations, for example power stations, transportation, communications and computers, which have all become critical to society and the modern world in which we live.

Electronics and electricity have come a long way since they were first being discovered. That is not to say that what was originally thought is now wrong or obsolete, but rather has been added to or has been more refined. When most people think of electricity what comes to mind is Ben Franklin with his kite and a key in the middle of the storm. However, that is only one completely minor detail which led to the discovery and the ability to harness and use what was already happening in nature. Only on a scale that could be used by an everyday person. Although it is something we all use every day, most people do not really know who or what has been done in the field of electronics and electricity. Most just take for granted the fact

Electromagnetic fields, or EMFs, is sometimes referred to as radiation. We are exposed to EMFs almost all the time. Almost all of the electronics or powered devices have some sort of electromagnetism in them. This includes your cell phone, kitchen appliances, television, lights, and computer. Electric door bells also use electromagnetic fields. When the button is pushed it signals for the coil to get electrified, then the bell sounds all because of the electromagnetic force.

This project has been executed by taking the different electricity generation of Geelong house of different sources of electrical energy and is been compared with other smart electrical energy.

An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earth's magnetic field, or through fridge magnets or magnets on children's toys. Magnetic forces are explained in terms very similar to those used for electric forces:

The link between Magnetism and electricity became evident in 1820. This relationship is important because electricity develops by the spinning of magnets around a coil of copper wire. In order to produce electricity a fuel source must spine the magnets. Electricity can be used from anything from communication sistemes to the everyday lightbulb.

Motorized switches: compact switches installed at the exit of the power generation points and at the entrance of energy consumption points in the electricity distribution system are integrated into the automation system by adding some additional equipment.Compact switches: Thanks to their high current limit capacities, they suppress short-circuit currents as soon as they occur and thus effectively protect all electrical equipment from wear that is often caused by short circuits.

The more electric aircraft (MEA) is a concept which describes the use of electronics in the existing airplane designs. As per (Kostakis, et al., 2014) cabin pressurization, air-conditioning and anti-ice wing protection require pneumatic power, flight surface actuation, landing gear and breaking require hydraulic power, and finally, engine fuel and oil pumps require mechanical power. Electrical power is limited to cabin lights, fans and avionics. However, on a MEA electrical power is used to power some or all the above mentioned loads. Additionally, two new technological features are incorporated on a MEA, the bleed-less engine and the electrical self-start of the engine. In a bleed-less engine, all of the air-intake is converted into thrust, without it having to be bypassed away from the compressors, as it would in a conventional engine, to power pneumatic loads. Bleed air is still required on the engine for operability reasons, but by reducing the amount of bleed-air required, this could allow the removal of some heavy equipment such as fans and ducts, and provides potential improvements in engine reliability. This architectural shift has brought benefits such as weight reduction, optimized performance and reduced life-cycle costs for the plane operator. Nonetheless, the increase in on-board electrical energy

Aim: The aim of the experiment is to investigate what affects the strength of an electromagnet.
