Magnetic Vector Potentials and Helicity in Periodic DomainsSimon Candelaresi
Magnetic helicity is often assumed to be gauge independend in periodic domains. Here I show that for triply periodic domains this is no the case if we allow for gauge fields which are not periodic. Using methods of p-forms from differential geometry it is shown that the magnetic vector potential does not exist for periodic domains with net magnetic flux through the boundaries. This has ramifications for numerical codes which make use of the magnetic vector potential, rather than the magnetic field.
This power point presentation includes concept of beam, types of beam, types of support, concept of shear force and bending moment diagram, concept of determinate and indeterminate beams, rules to draw SFD and BMD and numerical based on above said topic. It also includes concepts of drawing loading diagram and bending moment diagram from shear force diagram and numerical based on this concept.
it contains the basic information about the shear force diagram which is the part of the Mechanics of solid. there many numerical solved and whivh will give you detaild idea in S.f.d.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
2. I respect and thank our
physics teacher for giving an opportunity to do the
project work on Basic Law of Magnetostatics in
differential form and providing me all support and
guidance which made me complete the project on
time. I am extremely greatful to him for providing
such a nice support and guidance though he had
busy schedule managing the time .
3. Basic Law of Magnetostatics in Differential Form :
.B = 0 and × B =µ0J :-
There Are the following two fundamental laws of
magnetostatics :
(1) Div B = 0 or .B = 0
(2)Curl B = µ0 J or × B =µ0J
Law(2)- Curl B = µ0J or × B = µ0J :- The
Curl of the static magnetic field B produced near a
current carrying conductor is equal to the product if
permeability of the medium and current density. Thus the
magnetic field is a rotational (or Curl) field .
In differential form, Curl B = µ0 J or × B =µ0J (in air
or vacuum)
4. Proof :- If a stationary current (i.e., current not
changing with time) flows in a conductor, a magnetic field
is produced around it . According to Ampere’s circuital
law,
“the line integral of magnetic field vector B along a closed
curve in this magnetic field is equal to µ0 times the
algebraic sum of currents enclosed within that curve. Here
µ0 (= 4Π × 10-7 N/A2 ) is the permeability if free space.
Thus
B . dl = µ0 I ---------- 1st
Here the symbol expresses the line integral
along the closed curve .

5. The sign if integral depends on the direction of magnetic field. If
the direction of magnetic field is along the path, the line integral
is positive and if the direction of magnetic field is opposite to the
path, the line integral is negative .
For a stationary current, the total current enclosed within a
closed curve is equal to the flux of current density linked with the
area enclosed by that curve . Fig shows a volume distribution of
current in which the current density is J at a point (x , y , z) .
Consider a closed curve C around this point which encloses a
surface S . The current enclosed within the closed curve is
6. I = J . da
so, By Ampere’s law (from eqn. 1st ),
B . dl = µ0 J. da --------------2nd
But by Stokes's theorem , B. dl = Curl B. da
From eqn. 2nd , Curl B. da = µ0 J. da
or (Curl B - µ0 J ) . da = 0 or Curl B - µ0J = 0
or Curl B = µ0 J or × B = µ0 J.
