ve a vertical cylindrical magnetic rod as shown in Fig 5E 69 The axis of symmetry of the ring is the same as that of the rod The cylindrically symmetrical magnetic field around the ring can be described approximately in terms of the vertical and radial components of the magnetic field vector as B B 1 02 and B Bo r where Bo a and are constants and z andr are the vertical and radial position coordinates respectively B Properties of the ring Mass Radius B Fig 5E 69 Initially the ring has no current flowing in it When released it starts to move downwards with its axis still vertical From the data below determine how the ring moves subsequently What current flows in the ring Data m 50 mg To 0 5 cm Inductance L 1 3 108 H Initial coordinates of the centre of the ring z 0 r 0 motic fold constants
