A current I =2.5 (1+2t)×10^3A increase at a steady state in a long straight wire. A small circular loop of radius 10−3 m has its plane parallel to the wire and is placed at a distance of 1 m from the wire. The resistance of loop is 5 pie ×10^−4(Ω). Find the approximate value of induced current in the loop.

Space is divided by the line AD into two regions. Region I is field free and the Region II has a unifrom magnetic field B direction into the plane of the paper. ACD is a simicircular conducting loop of radius r with center at O, hte plane of the loop being in the plane of the paper. The loop is now made to rotate with a constant angular velocity ω about an axis passing through O and the perpendicular to the plane of the paper. The effective resistance of the loop is R. (i) obtain an expression for hte magnitude of the induced cureent in the loop. (ii) Show the direction of the current when the loop is entering into the Rigion II. Plot a graph between the induced e.m.f and the time of rotation for two periods or rotation.

Figure (a) shown two circular rings of radii a and b (a>b) joined together with wires of negligible resistance. Figure 3.15(b) shown thew pattern obtained by folding the small loop in the plane of the large loop. The pattern shown in Fig.3.15( c ) is obtained by twisting the small loop of Fig.3.15(a) through 180∘. All the three arrangement are placed in a uniform time varying magnetic field dB/dt=k, perpendicular to the plane of the loops. if the resistance per unit length of the wire is λ, then determine the induced current in each case.

A wire loop is suspended from a string that is attached to point P in the drawing. When released, the loop swings downward, from left to right, through a uniform magnetic field, with the plane of the loop remaining perpendicular to the plane of the paper at all times. (a) Determine the direction of the current induced in the loop as it swings past the locations labeled I and II. Specify the direction of the current in terms of the points x, y and z on the loop (e.g.x y, or . The points x , y, and z lie behind the plane of the paper. (b) What is the direction of the induced current at the locations II and I when the loop swings back, from right to left? Provide reasons for your answers.
