square wire frame is made of uniform wires with each side being 0.2 meters long, as shown in the below figure. Here, only the left half of the square is placed in a uniform magnetic flux density perpendicular to the page. The resistance is 10 Ω and assume that the conductor joining the two ends of the resistor is ideal. When the magnetic flux density increases by 10 Wb/m2 per second, determine the direction and magnitude of the current I flowing through the resistor.

Direction is upward according to Lenz law
emf generates is 10* 0.2*0.1 = 0.2 ( area is half of total area)
therefore current is 0.2/10 =0.02
