- - - - unit B; tesla, T
- - - - constant μ0 is called the permeability of free space
        
        μ0 = 4π x 10−7 T·m/A
- - - - formula
      - solenoid acts like a magnet. One end can be considered as
        the north pole, and the other as south pole
- - - - magnetic moment, μ
        
        the magnetic moment per turn, times the number of turns
      - μ = NIAB
        
        quantity NIA is called the magnetic dipole
        moment, M
