In Fig.  29.1, a  wire and a  10 - Ω   resistor  are used  to form a  circuit in  the shape  of a  square, 20  cm by 20  cm. A  uniform  but  nonsteady  magnetic  field is  directed  into the  plane of  the  circuit.  The  magnitud e of the  magnetic  field is  decreased  from  1.50 T to  0.50 T in  a time  interval of  32 ms.  The  average  induced  current  and its  direction  through  the  resistor,  in this  time  interval,  are  closest to:

A long  vertical  wire  carries a  steady 10 - A current.  A pair of  rails are  horizontal  and are    apart. A  20 - Ω   resistor  connects  points  and  b , at  the end of  the rails.  A bar is  in contact  with the  rails, and  is moved  by an  external  force with  a constant  velocity  of    as shown.  The bar  and the  rails have  negligible  resistance . At a  given  instant  the bar is    from the  wire, as  shown. In  Fig.  29.3a, at  time  t 1 the  induced  current  and its  direction  through the resistor are closest to:

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
