Electricity and Magnetism
Maxwell's equations for electromagnetism have been called the " second great unification in physics "  where the first one had been realised by Isaac Newton. With the publication of " A Dynamical Theory of the Electromagnetic Field " in , Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. Maxwell is also regarded as a founder of the modern field of electrical engineering. He helped develop the Maxwell—Boltzmann distribution , a statistical means of describing aspects of the kinetic theory of gases. He is also known for presenting the first durable colour photograph in and for his foundational work on analysing the rigidity of rod-and-joint frameworks trusses like those in many bridges. His discoveries helped usher in the era of modern physics, laying the foundation for such fields as special relativity and quantum mechanics. Many physicists regard Maxwell as the 19th-century scientist having the greatest influence on 20th-century physics.
His main discoveries include the principles underlying electromagnetic induction , diamagnetism and electrolysis. Although Faraday received little formal education, he was one of the most influential scientists in history. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. His inventions of electromagnetic rotary devices formed the foundation of electric motor technology, and it was largely due to his efforts that electricity became practical for use in technology. As a chemist, Faraday discovered benzene , investigated the clathrate hydrate of chlorine, invented an early form of the Bunsen burner and the system of oxidation numbers , and popularised terminology such as " anode ", " cathode ", " electrode " and " ion ". Faraday ultimately became the first and foremost Fullerian Professor of Chemistry at the Royal Institution , a lifetime position. Faraday was an excellent experimentalist who conveyed his ideas in clear and simple language; his mathematical abilities, however, did not extend as far as trigonometry and were limited to the simplest algebra.

In this format, classes are held three times a week, twice in a two-hour block, and once in a one-hour block. Students sit at tables of nine in a specially designed classroom, with three groups of three students at each table. Mini-lectures are interspersed with desktop experiments and group problem solving and discussion. The one-hour session on the third session of the week is reserved entirely for problem solving.
Electric current flowing through a wire creates a magnetic field that attracts ferromagnetic objects, such as iron or steel. This is the principle behind electromagnets and magnetic levitation trains. It allows cranes to pick up whole cars in the junkyard and makes your doorbell ring. You can read about it here , and then watch it work when you do these experiments. Adult supervision recommended.

Electricity and magnetism are integral to the workings of nearly every gadget, appliance, vehicle, and machine we use. This unit explains electricity, from charged particles at the atomic level to the current that flows in homes and businesses. There are two kinds of electricity: static electricity and electric currents.
Танкадо - мастер высокого класса, он никогда не оставил бы висячие строки, тем более в таком количестве. Эти висячие строки, или сироты, обозначают лишние строки программы, никак не связанные с ее функцией. Они ничего не питают, ни к чему не относятся, никуда не ведут и обычно удаляются в процессе окончательной проверки и антивирусной обработки. Джабба взял в руки распечатку.
Да, а как зовут вашего брата. Я скажу вам, кто его сегодня сопровождает, и мы сможем прислать ее к вам завтра. - Клаус Шмидт, - выпалил Беккер имя из старого учебника немецкого.
Он не мог понять, почему Мидж всегда права.
