Domain and range if there are two sets a and b and relation r have order pair x y then.
													
																	Relation between b and h formula. 
									
	
		
	
																	Where θ is the angle between the wire and the field direction. 
																	If the medium is non continuous or anisotropic then magnetic poles or a demagnetising field could be created which themselves become sources of local excitation and they add to the source. 
																	A relation is just a set of ordered pairs. 
																	The quantity m in these relationships is called the magnetization of the material. 
															
													
									
	
		
	
																	Relation between a m g m. 
																	Bio savart law gives us b which i suppose is magnetic field. 
																	But i have read in many places h is magnetics field and is defined as and we have relation as b mu0 h where b is magnetic flux density. 
																	In the end both b and h are just abstractions which the maths can use to model magnetic effects. 
															
													
									
	
		
	
																	Thus b is related to the properties of the material and its relation to the applied excitation e g. 
																	It will be shown later that this relationship is due to the empirical relationship between the h field and the magnetic field b b μh where μ is the permeability of the material. 
																	There is absolutely nothing special at all about the numbers that are in a relation. 
																	Like ohm s law hopkinson s law can be interpreted either as an empirical equation that works for some materials or it may serve as a definition of reluctance. 
															
													
									
	
		
	
																	Electric current can be highly non linear. 
																	To further distinguish b from h b is sometimes called the magnetic flux density or the magnetic induction. 
																	B μ 0 h m h and m will have the same units amperes meter. 
																	The vacuum permeability μ 0 is by definition 4π 10 7 v s a m. 
															
													
									
	
		
	
																	Where χ is called the volume magnetic susceptibility and. 
																	0 1 2 3 4 5 these numbers are grouped as 3 s so not ordered and therefore not a relation 1 7 3 4 5 5 one more time. 
																	B μ m h. 
																	These three are average or mean of the respective series. 
															
													
									
	
		
	
																	Another commonly used form for the relationship between b and h is. 
																	In other words any bunch of numbers is a relation so long as these numbers come. 
																	So it seems that h describes the way magnetism is generated by moving electric charge which is what a current is while b is to do with the ability to be detected by moving charges. 
																	In diamagnets and paramagnets the relation is usually linear. 
															
													
									
	
		
	
																	A relation between m and h exists in many materials.
