Problem 1: A 3.0-cm-diameter (Dc), 10-turn coil of wire, located at z = 0 in the xy-plane, carries a current I = 2.5 A. A 2.0-mm-diameter (D₁) conducting loop with R = 2.0 × 10-¹2 resistance is also in the xy-plane at the cen- ter of the coil. At t = 0s, the loop begins to move along the z-axis with a constant speed of v= 75 m/s. What is the induced current in the conducting loop at t = 200 µs? 10 turns ZA al FQI I FIG. 1: The scheme for Problem 1 a) The magnetic field created by the coil looks in general as shown in Fig. 1, but since the diameter of the loop is much smaller than that of the coil, we can use the formula for the on-axis magnetic field of IR² the coil.

Hello, I really need help with Part A, PART B, AND PART C BECAUSE I don't understand it is there any chance you can help me with the problems and can you label them as well

Problem 1: A 3.0-cm-diameter (De), 10-turn coil of wire, located at z = 0 in the xy-plane, carries a current I = 2.5 A. A 2.0-mm-diameter (D₁) conducting loop with R= 2.0 × 10-4 resistance is also in the xy-plane at the cen- ter of the coil. At t = 0s, the loop begins to move along the z-axis with a constant speed of v = 75 m/s. What is the induced current in the conducting loop at t = 200 µs? 10 turns ZA I FIG. 1: The scheme for Problem 1 a) The magnetic field created by the coil looks in general as shown in Fig. 1, but since the diameter of the loop is much smaller than that of the coil, we can use the formula for the on-axis magnetic field of Но IR² the coil. For a single turn of the coil, this formula gives B = where Re is the radius of the coil. 2 (2²+R²) 3/2 Derive the formula for the magnetic flux through the conducting loop as a function of the coordinate z. b) Derive the formula for the emf, E = |d, induced in the loop as it is moving up. To take the derivative of flux with respect to time, you need to use the chain rule for derivatives, d=dd. What is the meaning of in this formula, and how does z depend on time? Express & as a function of t. c) Using the formula for & from the previous step and the resistance of the loop, compute the value of the induced current at t = 200 µs. (Answer: loop = 4.4 x 10-² A)
