圆形线圈套在辐向永久磁铁槽中,磁场的磁感线均沿半径方向均匀分布,此时形成的磁场就叫做辐向磁场.辐向磁场特点是:距轴线等距离处的磁感应强度的大小总是相等的,磁感应线总沿着轴向均匀分布.这种辐向分布的磁场在教学中常常被边缘化,容易被教师和学生忽略.本文从辐向磁场分布的特点及应用展开讨论一、磁电式电流表
Circular coil sets in the radial permanent magnet slot, the magnetic induction lines are evenly distributed along the radial direction, the magnetic field formed at this time is called the radial magnetic field.The radial magnetic field is characterized by: magnetic induction at equal distances from the axis of the intensity The size is always the same, the magnetic induction line along the axial uniform distribution of this radial distribution of the magnetic field in teaching often marginalized, easily overlooked by teachers and students.This article from the radial magnetic field distribution characteristics and applications are discussed First, the magnetic ammeter
