A ten-turn circular wire loop with a radius of 1 cm and resistance 0.10 Ω is held stationary above a vertically aligned solenoid as shown in the diagram. The solenoid is attached to a power supply similar to the ones in lab, and the sense in which the current flows through the solenoid is clockwise as viewed from above. The solenoid creates a nearly homogeneous magnetic field near the wire loop with magnitude B = 0.002 T at t = 0 s.
Between times t = 2 s and t = 4 s, the current of the power supply is steadily increased (i.e., the rate at which the current through the solenoid increases is constant) until the current through the solenoid is doubled as shown in the graph of Isol(t).
At t = 1 s, the direction of the magnetic field near the center of the wire loop is (up/down)? when you look at it from above is the current (CW/CCW/ZERO). what is the magnitude of the flux through the loop?
At t = 3 s, the direction of the magnetic field near the center of the wire loop is (up/down)? when you look at it from above is the current (CW/CCW/ZERO). what is the rate of change of the flux in the loop? What is the EMF?
