CBSE Class 12 Physics Formulae Magnetic Effect Of Current And Magnetism Notes

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets , producing magnetic fields themselves. Demagnetizing a magnet is also possible. Only a few substances are ferromagnetic; the most common ones are iron , cobalt and nickel and their alloys.

CBSE Class 12 Syllabus For Physics 2020-21 (Reduced And Updated)

Question 1. The magnetic field at the center O of the following current loop is- Answer:. Question 2. Question 3. Question 4. A circular coil of radius 5 cm and 50 turns carries a current of 3 ampere.

Magnetism is known since from the time of ancient Greeks, but it has always been a bit mysterious. You can see the electricity in the flash of a lightning bolt, but when a compass needle points to the magnetic north, you cannot see any force causing it to rotate. You must have studied about the electrostatic fields and forces, which are caused by the electric charges at rest and these electric fields can move other free charges, like by producing a current in a circuit. It is known that, when an electric charge moves, it generates other fields and forces. The additional fields and forces are known to as magnetism. Biot - Savart law and the application to current carrying circular loop.

Register Now. Hey there! We receieved your request. Magnetic fiel d:- Magnetic field, of any magnetic pole, is the region space around it in which its magnetic influence can be realized. Lines of Force Flux Lines :- Line of force is the path along which a unit north pole would move if it were free to do so.

Then, what about the reverse possibility of an electric effect of moving magnets? In this Chapter we will study magnetic fields and such electromagnetic effects. We.

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. The attached concepts will help the student to understand the chapter and score better marks in the examinations. It is a region around a magnet or current carrying conductor in which its magnetic influence can be felt by a magnetic needle.

Оказавшись на улице, человек в очках в тонкой металлической оправе достал крошечный прибор, закрепленный на брючном ремне, - квадратную коробочку размером с кредитную карту. Это был опытный образец нового компьютера Монокль, разработанного ВМС США для проверки напряжения аккумуляторов в труднодоступных отделениях подводных лодок - миниатюрный аппарат, совмещенный с сотовым модемом, последнее достижение микротехнологии. Его визуальный монитор - дисплей на жидких кристаллах - был вмонтирован в левую линзу очков.

О Боже! - воскликнул он в ужасе. - Esta muerta, - прокаркал за его спиной голос, который трудно было назвать человеческим.
