In the figure shown the wires AB and PQ carry constant currents I_(1) and I_(2) respectively. PQ is of uniformly distributed mass ‘m’ and length ‘l’ AB and PQ are both horizontal and kept in the same vertical plane. The PQ is in equilibrium at height ‘h’. Find ‘h’ is terms of I_(1) I_(2) , l, m, g and other standard constants.

1.	In the figure shown the wires AB and PQ carry constant currents I_(1) and I_(2) respectively. PQ is of uniformly distributed mass ‘m’ and length ‘l’ AB and PQ are both horizontal and kept in the same vertical plane. The PQ is in equilibrium at height ‘h’. Find ‘h’ is terms of I_(1) I_(2) , l, m, g and other standard constants.
Answer» SOLUTION :MAGNETIC repulsive force balnaces the WEIGHT. `(mu_(0)I_(1)I_(2))/(2pih)l=mgimpliesh=(mu_(0)I_(1)I_(2)l)/(2pimg)`

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 ?
