(Be30o11) A square wire with \( 2 \mathrm{~m} \) sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in the figure. The loop contains a \( 20 \mathrm{~V} \) battery with negligible resistance. If the magnitude of the field varies with time according to \[ B=1.0910-0.9900 t \] with \( B \) in teslas and \( t \) in seconds, what is the total emf in the circuit? Tries or \( / 4 \) What is the direction of the current through the battery? counterclockwise cleckwise Thies \( 0 / 4 \) This discussion is closed.
