-Faraday- his major contributions were in the fields of electromagnetism and electrochemistry. He explained the basis of magnetic field through his studies on the effects of magnetic field around a conductor which carried Direct Current (DC). In 1831‚ Faraday made one of his most renowned discoveries‚ the principle of electromagnetic induction by using the "induction ring". The electricity was generated by means of electromagnetic effect. This was the first version of an electric transformer. He

What is Magnetism? Properties of Magnets: Magnet: any material that attracts iron and materials that contain iron Magnets attract iron and materials that contain iron. magnets attract or repel other magnets. In addition‚ one part of a magnet will always point north when allowed to swing freely. Magnetic Poles: Magnetic Pole: any magnet with 2 ends‚ each is called a magnetic pole. Magnetic poles that are unlike attract each other and magnetic poles that are alike repel each other. Magnetic

universe is governed by four fundamental forces‚ or interactions. These forces are the strong nuclear force‚ weak nuclear force‚ electromagnetic force‚ and gravity. The first two forces work on the atomic level but we can observe gravity and electromagnetism every day. Without these four fundamental forces of nature working together‚ our world would break apart and float aimlessly into oblivion. The strongest of the four fundamental forces of nature is the strong nuclear force‚ also called the strong

Most students of electricity begin their study with what is known as direct current (DC)‚ which is electricity flowing in a constant direction‚ and/or possessing a voltage with constant polarity. DC is the kind of electricity made by a battery (with definite positive and negative terminals)‚ or the kind of charge generated by rubbing

Electricity is important in our everyday lives. It is essential for almost everything in our modern world. The knowledge learned in the past about electricity enabled such things as engines‚ telephones‚ radios‚ computers‚ and much‚ much more. As early as 600 B.C.‚ the Greeks were already studying electricity. They noticed that if you rubbed a piece of amber with fur‚ it had a charge with the ability to attract small objects. Many years later‚ in the 16th Century‚ William Gilbert discovered many

Wireless Charger for Low Power Devices Chapter 1 1.1 Introduction We live in a world of technological advancement. New technologies emerge each and every day to make our life simpler. Despite all these‚ we still rely on the classical and conventional wire system to charge our everyday use low power devices such as mobile phones‚ digital camera etc. and even mid power devices such as laptops. The conventional wire system creates a mess when

What is Electricity? Electricity is one of the most powerful forces in our lives. As a matter of fact‚ it can even kill you. The most vital part of electricity is called electric energy. This is what we commonly think of when we hear the word electricity. “Electricity” reminds us of anything that we plug into an electrical outlet in order to make it work‚ such as lights‚ refrigerators‚ video games‚ microwaves‚ and computers. Scientists discovered ways to produce electric energy in large amounts
