# Sound Current Conducting wire (free current) +ze (bound) -e (bound) (air filling) magnetic moment m^2 = (2πao^2) * (A/2) many types of Magnetic moment (Orbital + Spin + mucleus) For Example Iron filled Solenoid Bnet = Bfree + Bbound for air (vacuum) or free space ⇒ Bbound = 0 interaction b/w Bbound and Bfree (1) Diamagnetic (Cu, Ag etc) ⇒ Bbound is opposite to Bfree (2) Paramagnetic (Cr, Al etc) ⇒ Bbound and Bfree in same dirn (3) Ferromagnetic (Fe, Ni, Co) ⇒ Bbound and Bfree in same dirn Dia Para Ferro (165) Density 90 Dia. < 120 Para. < 200 Fero. ϕ = No. of magnetic flux line ϕ = weber = 100 weber
