about magnetic flux
A loudspeaker magnet has a circular air-gap of inner diameter d1=22mm,outer diameter d2=24mm ,and depth h=8mm to accommodate the oscillation coil.If the air-gap has magnetic flux density B=0.75Wb/m2 ,find the magnetic flux that must be produced for a flux leakage of 15%.
498.6μWb
