1.	A solenoid has core of a material with relative permeability 500 and its windings carry a current of 1 A. The number of turns of the solenoid is 500per meter. The magnetization of the material is nearlyA. `2.25xx10^(3)Am^(-1)`B. `2.25xx10^(5)Am^(-1)`C. `2.0xx10^(3)Am^(-1)`D. `2.0xx10^(5)Am^(-1)`
Answer» Correct Answer - B Here, n=5000turns/m `I=1A, mu_(r)=500` `"Magnetic intensity", H=nI=500m^(-1)xx1A=500Am^(-1)` `As, mu_(r)=1+chi` Where, `chi` is the magnetic susceptibility of the material `or chi=(mu_(r)-1)` Magnesium, `M=chiH` `=(mu_(r)-1)H=(500-1)xx500Am^(-1)` `=499xx500Am^(-1)=2.495xx10^(5)Am^(-1)` `approx 2.5xx10^(5)Am^(-1)`
