3. Please increase the video quality of future videos , cant see pointer also
4. difficult to notice the cursor ( pointer )
5. sir you are awesome.. will attend your classes from monday
6. I love you 😚😚😚
7. This program used in presentation is amazing !!! Does anyone know which software is this?
8. I really appreaciate these lectures, but concerning to this particular one I really prefer to think about changing the concatenated flux through the coil instead of considering different directions of the flux. It just does not make much sense to me. Since "concat. flux" = B.A (scalar product between B, the vector representing the magnetic field from north to south pole and A, the vector which is normal to the coil surface), this product changes during coil movement (direction of vector A changes), so that "concat. flux" = |B|.|A|.cos wt, where wt is the angle between the area vector and the magnectic field.
   
   Anyone agrees ?
9. such a detailed lecture ... awesome ... even dummies can learn by watching this video !!!
10. awesome way of teaching....:)
11. very good lecture
12. Bore but good lecture ...
