How (Figure 1) shows a 4.0-cm-diameter loop with resistance 0.17 Ω around a 2.0-cm-diameter solenoid.  The solenoid is 11 cm long, has 100 turns, and carries the current shown in the graph (Figure 2). A positive current is cw when seen from the left. Find the current in the loop at t = 0.5 s. Express your answer as an integer and include the appropriate units. I(0.5) =

how do i solve this question?

A flexible circular loop 8.00 cm in diameter lies in a magnetic field with magnitude 2 T, directed into the plane of the page in the figure. The loop is pulled at the points indicated by the arrows, forming a loop of zero area in 0.300 s. Find the average induced emf in the circuit.  What is the direction of the induced magnetic field  What is the direction of the induced current in R? (From a to b or b to a)  If you rotate the circular loop as the top part out of page, what is the direction of the induced current in R? (From a to b or b to a) If you move the circular loop inside the magnetic field with a constant velocity toward the right, what is the direction of the induced current in R? (From a to b or b to a)

At time t = 0, the switch is closed in the circuit shown. What is the current through resistor R3 immediately after the switch is closed? Vo R1 R3 R2 (R,+R;) O V(R,+R,+R;) R, (R,+R3)

In (Figure 1), R = 16.0 Ω and the battery emf is 6.30 V. With switch S2 open, switch S1 is closed. After several minutes, S1 is opened and S2 is closed. Part A At 2.50 ms after S1 is opened, the current has decayed to 0.300 A. Calculate the inductance of the coil. Part B How long after S1 is opened will the current reach 1.00% of its original value?

Please don't provide handwritten solution ....

The loop in the figure below is rotated out of the plane of the drawing while B is kept constant. You can assume the rotation axis is along the horizontal direction in the figure. a) Does the magnitude of the flux through the loop increase or decrease with time? (Assume the loop has not had time to rotate by more than 90°.) Increase/Decrease? b) If the loop has only rotated a small amount, will the induced current be clockwise or counterclockwise?

Please box answer for D.

I'm working on some homework and am stumped with this problem.  Help would be great, thanks!

In figure 1, suppose that ε = 69.0 V, R = 250.0 ohms, and L = 0.170 H. Which switch S2 open, switch S1 is left closed until a constant current is established. Then S2 is closed and S1 is opened, taking the battery out of the circuit. Part A: What is the initial current, just after S2 is closed and S1 is opened, then determine the current in the resistor at t = 4.50x 10^-4 s. Part B: What is the potential difference between points b and c at t = 4.5 x 10^-4 s, then determine which point is at a higher potential (b or c)? Part C: How long does it take the current to decrease to half its initial value? Answer in seconds. Thank You for the help in advance!
