Amperes circuital law applications
Asked by nehamerslyn | 16 May, 2019, 11:37: AM
answered-by-expert Expert Answer
Ampere's law gives magnetic field induction B at a radial point of circulr line that encloses the current carrying conductors.
Magnetic field induction B is expressed in terms of current flowing in conductors.
 
begin mathsize 12px style contour integral subscript C B times d s space equals space mu subscript 0 space I end style 
 
This law is useful to get magnetic field due to currents under the conditions of certain symmetry. As a simple application,
we can derive magnetic induction at a point due to a long straight current carrying conductor

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
