The figure shows an arbitrarily shaped planar conducting loop A in the XY plane. Two nonintersecting regions with areas  and  within the loop are subjected to magnetic fields  , and , respectively.

What is the expression for the induced rms voltage in loop A?

A rotating conductor of 1 m length is placed in a radially outward (about the z-axis) magnetic flux density ((B) of 1 Tesla as shown in the figure below. Conductor is parallel to and at 1 m distance from the z-axis. The speed of the conductor in r.p.m. required to induce a voltage of 1V across it, should be ___________.

Consider a one – turn rectangular loop of wire placed in a uniform magnetic field as shown in the figure. The plane of the loop is perpendicular to the field lines. The resistance of the loop is  and its inductance is negligible. The magnetic flux density (in Tesla) is a function of time, and is given by B(t) =0.25sin , where radian/second. The power absorbed (in Watt) by the loop from the magnetic field is

A circular turn of radius 1m revolves at 60rpm about its diameter aligned with the x – axis as shown in the figure. The value of  is  is SI unit. If a uniform magnetic field intensity  A/m is applied, then the peak value of induced voltage, (in Volts), is _____________.

The laws of electromagnetic induction (Faraday’s and Lenz’s law) are summarized in the following equation:

An infinitely long straight wire carries 1000A of current and in the vicinity there is a circular conducting loop of 100mm diameter with the center of the loop 1m away from the straight conductor. Both the wire and the loop are coplanar. Determine the magnitude and direction of current in the loop that produces a zero flux density at its center.

A square coil of turns and 10cm side is moved through a steady magnetic field of  at a constant velocity of 2m/sec with its plane perpendicular to the field as shown in figure. Plot the variation of induced e.m.f as the coil moves along the field.

Static magnetic fields induce currents in closed conducting loops. ( True=1, False=0)
