Please just help with this question: What would be the terminal velocity of the rod if all the conditions of part (b) of the problem where held, except there was also friction with a kinetic coefficient of ?k=0.0215? (Note: I believe the answer for b) is the induced current of 0.049 A if it helps)
A straight conductor carrying current i=5.0 A splits intoidentical semicircular arcs as shown in Fig. 2. What is themagnetic field at the center C of the resulting circular loop?Please explain your result.
As shown below, a square loop of wire of side a moves through a uniform magnetic field of magnitude B perpendicular to the page at constant velocity, vector v, directed to the right. Which statement regarding the electric field induced in the wires is correct for the wires at the left and right sides of the loop? (Hint: Be careful of what is being asked here. I am not asking for the direction of current.)
Please help me with this problem. A conducting rod of length A is moved with a uniform velocity v, into a circular region of constant magnetic field B.(The small circles are to show the B-field is out of the page and perpendicular to the plane of the loop.)The field B is confined in a circular region and is perpendicular to the plane of the circle of radius R, and the moving rod. Let A = 2R, where R is the radius of the circular loop. (a)With some explanation provided, what is the direction of the induced current? (b) What is the induced emf induced in the rod at any time t?

The arrangement illustrated in the figure below is composed of six finite straight wires of length l. The electric current flowing in such an arrangement is i. Using the Biot-Savart law, calculate: The magnitude of the magnetic field at point P due to the wire located along segment ab.The answer is in the second image. I am trying to use the standard biot-savart, which is B = (μ0*I/4π) * ∫dl * sinθ / r^2, and it always gives me 16*pi*l at the denominator, instead of 8pi*l. Solve it using B = (μ0*I/4π) * ∫dl * sinθ / r^2, and note that the image with the answer is correct.
At a point P on the center axis of a magnetic field created by a sufficiently long solenoid, we divide the magnetic field strength vector into a circular loop of the solenoid coil as shown below to add all the magnetic fields they create. (Let's simplify to continuous which isn't continuous). Complete this task to show that the magnetic field strength is "first image"at P point.
