Notes for Electromagnetic Induction chapter of class 12 physics.

First Law: When magnetic flux linked with the conductor changes, induced emf produces across it.

Many applications are found using electromagnetic induction, including electrical components such as inductors and transformers, and devices such as generators and electric motors. Two different phenomena are described by Faraday's law: the transformer EMF which is generated by an electric force due to a changing magnetic field due to the differential form of the Maxwell—Faraday equation and the motional EMF generated by a magnetic force on a moving wire see Lorentz force. In , James Clerk Maxwell drew attention to the separate physical phenomenon.

Learning the important concepts is very important for every student to get better marks in examinations. The concepts should be clear which will help in faster learning. Magnetic flux is a scalar quantity and its SI unit is Weber Wb. According to Lenz law, the direction of induced current or the polarity of the induced e. Lenz law obeys the principle of energy conservation. The induced e. When a metal rod of length l is placed normal to a uniform magnetic field B and moved with.

List of topics to be covered in this chapter are as follows. Electromagnetic Induction. Eddy Currents. Let us go through these topics one-by-one. When changing current is passed through a closed coil, varying magnetic flux develops in it. Due to this flux, an emf is induced in the coil.

Electromagnetic induction is a phenomenon in which the rate of change of flux through a coil causes an induced emf. Due to this induced emf, an induced current is created inside the coil.

Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in , and James Clerk Maxwell mathematically described it as Faraday's law of induction. Lenz's law describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell—Faraday equation, one of the four Maxwell equations in his theory of electromagnetism. Electromagnetic induction has found many applications, including electrical components such as inductors and transformers , and devices such as electric motors and generators.

 - Ну. Я хорошо его знаю. Если вы принесете мне его паспорт, я позабочусь, чтобы он его получил. - Видите ли, я в центре города, без машины, - ответил голос.  - Может быть, вы могли бы подойти. - Понимаете, я не могу отойти от телефона, - уклончиво отозвался Ролдан.  - Но если вы в центре, то это совсем недалеко от .

Он поднял вверх голову, надеясь увидеть Гиральду, но окружившие его со всех сторон стены были так высоки, что ему не удалось увидеть ничего, кроме тоненькой полоски начинающего светлеть неба. Беккер подумал, где может быть человек в очках в тонкой металлической оправе. Ясно, что тот не собирался сдаваться. Скорее всего идет по его следу пешком.

 О Боже, - прошептал.  - Ну и мерзавец этот Танкадо. ГЛАВА 110 Невидящими глазами Джабба смотрел на распечатку, которую ему вручила Соши. Он побледнел и вытер рукавом пот со лба.

Он застонал. Проклятые испанцы начинают службу с причастия. ГЛАВА 92 Сьюзан начала спускаться по лестнице в подсобное помещение. Густые клубы пара окутывали корпус ТРАНСТЕКСТА, ступеньки лестницы были влажными от конденсации, она едва не упала, поскользнувшись. Она нервничала, гадая, сколько еще времени продержится ТРАНСТЕКСТ.
