(a) briefly describe the physical origin of bound currents in magnetised materials consider a thin slab of material with uniform magnetisation m. with the aid of a diagram and a qualitative argument, show that the volume bound current density is [5] 3. zero (b) a thin conducting cylindrical shell (or pipe) of radius a and infinite extent is symmetrical about the z-axis. it is surrounded by a linear magnetic material extending out to a cylindrical radius b in which the magnetic susceptibility varies smoothly with cylindrical coordinate as xm(s)= xoa2/s2 for a < s

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
