Ampere’s Law:-

It states that magnetic field generated by electric current is directly proportional to source's electric current with a permeability constant as a proportionality constant,

$\int Bdl={\mu}_{0}I$

Where

B=Magnetic field , I= current and ${\mu}_{0}$=Permeability constant

Importance of Ampere's Law

1. It gives us mathematical relationship between electric current and magnetic field used to find In long current-carrying wire the magnetic induction

2. it work as bridge between electricity and magnetism

3. the magnetic field produced by electric current moving in any shape of wire is calculated with the help of this law

In a truck-loading station at a post office, a small 0.200-kg package is released from rest a point A on a track that is one quarter of a circle with radius 1.60 m.The size of the packageis much less than 1.60m, so the package can be treated at aparticle. It slides down the track and reaches point B with a speed of 4.80 m/s. From point B, it slides on a level surface a distanceof 3.00 m to point C, where is comes to rest.

(a) What is the coefficient of kinetic friction on the horizontal surface?

(b) How much work is done on the package by friction as it slides down the circular arc from A to B?

Until he was in his seventies, Henri LaMothe excited audiences by belly-flopping from a height of 13 m into 35 cm. of water. Assuming that he stops just as he reaches the bottom of the water and estimating his mass to be 72 kg, find the magnitudes of the impulse on him from the water.

A constant potential difference of 12V is maintained between the terminals of a 0.25 micro-F parallel plate air capacitor.

A. A sheet of Mylar is inserted between the plates of the capacitor completely filling the space between the plates. When this is done how much additional charge flows into the positive plate of the capacitor? (K for mylar = 3.1)

B. What is the total induced charge on either face of the mylar sheet?

C. What effect does the mylar sheet have on the electric field between the plates? Explain how you can reconcile thiswith the increase of charge on the plates, which acts to increase the electric field.

Gauss's law for magnetism is stated as followed with the beautiful closed surface double integral :

$\underset{S}{\text{\u222f}\phantom{\rule{thinmathspace}{0ex}}}\mathbf{B}\cdot \text{d}\mathbf{A}=0$

As I understand, the idea is to say that if we sum (continuous sum since integral) all the scalar products between the vector field B (i.e., magnetic field) and surface elements dA defined by their surface normals, we get 0?
