1.	A recatangular loop made of a very thin and flexible wire is kept on a table. The two ends of the wire are connected with two joining screws and a high directe current is allowed to pass through the wire. What will be the shape of the wire and why ?
Answer» Solution :The rectangular loop is shown in Fig. 1.85. the DIRECTIONS of current in the partsAB and CD are parallel and opposite in directionand hence these two parts repel each other. If the current is too high, the loop will TAKE almost the shape of a circle, that shape is shown by dotted LINE in the figure.

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 ?
