In Figure (a), two concentric coils, lying in the same plane, carry currents in opposite direction. The current in the larger coil 1 is fixed. Current i_(2) in coil 2 can be varied. Figure (b) gives the net magnetic moment of the two-coil system as a function of i_(2). The vertical axis scale is set by mu_(net),s=2.0xx10^(-5) A.m^(2), and the horizontal axis scale is set by i_(2s)=10.0mA. If the current in coil 2 is then reversed, what is the magnitude of the net magnetic moment of the two-coil system when i_(2)=7.0 mA?

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
