Problem in Magnetic Field and magnetic effect of electric current

[Diganta28]

I read in class 10. I am having problem understanding magnetic fields, magnetic flux,magnetic flux density,magnetic field strength,magnetic permeability and strength of magnetic field produced due to a straight and closed loop current carrying conductor at a certain point at a certain distance from the conductor.
Please help me to understand this concepts.
I googled several times on this subject but the explanations given goes tangentially to my head.
Please let me easily understand this concepts...
