The current generator i g ​

In the circuit shown in Fig. A conducting wire HE is moved with a constant speed v towards left. The complete circuit is placed in a uniform magnetic field B perpendicular to the plane of circuit inwards. The current in HKDE is horizontal rails connected to i g ​ . The entire system lies in [...]

A metallic wire is folded to form a square loop of side a. It carries a current i and is kept perpendicular to the region of uniform magnetic field B. If the shape of the loop is changed from square to an equilateral triangle without changing the length of the wire and current. The amount [...]

The magnetic field in a region is given by B = B [ 1+ x/a ] k. A square loop of edge length d is placed with its edge along the x – and y axes. THe loop is moved with a constant velocity v = v0 i. The emf included in the loop is [...]

The current generator i g ​ , shown in figure, sends a constant current i through the circuit. The wire ab has a length l and mass m slide on the smooth, horizontal rails connected to i g ​ . The entire system lies in a vertical magnetic field B. The velocity of the wire [...]
