Unformatted text preview: Faradays Law 2 Given: F i n d : cm a 10 ? m 156 N ? 35 ? m ? A circular loop of radius a = 10 cm and N = 156 turns is fixed in the x- y plane. A spatially uniform magnetic field with only a z-component covers the entire area of the loop. The plot at the right shows B z measured in tesla versus time t measured in seconds. The + z direction is OUT of the screen. (a) Calculate the magnetic flux through the loop in the z-direction at the times indicated below. In each case, specify the direction by giving a positive value for flux in the + z direction and a negative value for flux in the - z direction. (b) Calculate the induced EMF (electromotive force) in the loop at the times specified below. In each case specify the sense of the EMF by giving a positive value for a counterclockwise EMF as viewed in the above figure; specify a clockwise sense by giving a negative value....
