Video: Force on a current carrying conductor placed in magnetic field

In continuation with earlier videos for Physics Class 12; a new video on an important topic titled above is being posted. The same is available on the following adress:

Happy Learning!

Videos….CYCLOTRON

The video deals with Cyclotron; a very important topic in class 12 CBSE Physics. To understand the same, it will be of great help if you watch the video ‘Motion of a charge in magnetic field.’

The relevant note are in the following file:

CYLOTRON

 

Videos….Lorentz force

The video describes Lorentz force and the effect of Magnetic field on K. E. of  charge moving in the field. It is a very important force and is used in CYCLOTRON; a topic usually asked in CBSE exams.

The link to the video is as under:

The next video will deal with CYCLOTRON.

Videos: Magnetic Effect of Current-4…….

Magnetic Effect of Current-4: The video is a sequel to Parts 1,2and 3. It describes the use of Ampere’s Circuital Law to obtain an expression for magnetic field due to a straight conductor and solenoids..

Magnetic Effects of Current-1 & 2….Videos

 In order to give you a feeling of the real Class room teaching learning process, we at physicsbeckons are trying to produce and present the CBSE Physics class 12 curriculum in the form of videos. Continuing the effort, two videos on the lesson Magnetic Effect of Current (Physics) class 12 are being uploaded.

The video Magnetic Effect of Current-1 is an introduction to discovery of the Magnetic Effect. The video Magnetic Effect of Current-2 deals with Biot-Savart Law and its applications  You may go through the videos carefully to understand the basic concepts involved and the applications thereof for solution of the numerical problems. Please make sure to reinforce learning by carefully going through any Text/reference book and try more numerical problems in order to gain the confidence and to reassure yourself that the lessons have been well understood.

In the next video Magnetic Effect of Current-3, we will continue with applications of Biot-Savart law. Numerical problems based on these concepts will also be covered in this video.

Your feedback is welcome.

Galvanometer

In continuation with the earlier parts of the Unit, Magnetic effects and magnetism, another simple but very important topic Galvanometer is being posted for your benefit.

The post contains the principle, construction and working of the galvanometer. This article on moving coil galvanometer is important and may be asked as a direct question.

In addition , it contains two sub-parts on conversion of galvanometer to ammeter and voltmeter.

Simple numerical problems are generally asked on these topics.

In order to reinforce understanding, sample problems on the conversions have also been included.
