magnetic induction
    The cross-section of the lectromagnet is 8.0cm×5.5cm2 and its gap is 1.3 cm. the magnetic induction B may reach 0.15 T. If the gap is reduced by magnetic pads,a maximum Bmax of 1.5 T may be obtained.
    电磁铁截面积为8.0cm×5.5cm,间隙为1.3cm,磁感应强度B可达0.15T,如缩小间隙,Bmax可达1.5T。
    (4)The relation of magnetic induction and the signal output is linear under low magnetic field through analyzing data.
