A wire is sliding as shown in Figure. The angle between the acceleration and the velocity of the wire is

A horizontal wire carries a current as shown as shown in Figure below between magnetic poles N and S : Is the direction of the force on the wire due to the magnet :

A conducting wire is bent in the form of an angle theta . The wire moves with velocity v along the bisector of angleA'OB' as shown in figure. Find the emf induced between the two ends of the wire if a magnetic field is acting perpendicular to the plane of the paper and directed into it.

A cube is constructed by connecting 12 wires of equal resistance as shown in figure. The equivalent resistance between the points A and B shown in the figure is..... . The resistance of each wire is of r Omega . A and B are the midpoints of the sides PQ and VU respectively.

A pearl of mass m is in a position to slide over a smooth wire .At the intial instant the pearl is in the middle of the wire ,The wire moves linerly in a horizontal plane with an with the acceleration of the pearl Q.r.t wire is -

Consider the situation shown in the figure. The wire Ab is sliding on the fixed rails with a constant velocity. If the wire AB is replaced by semicircular wire, the magnitude of the induced current will

A wire, which passes through the hole in a small bead, is bent in the form of quarter of a circle. The wire is fixed vertically on ground as shown in the figure. The bead is released from near the top of the wire and it slides along the wire without friction. As the bead moves from A to B, the force it applies on the wire is
