A conducting rod of length L 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.).

solve a and b please. A permanent magnet in the shape of a right circular cylinder of length L and radius R is oriented so that its symmetry axis coincides with the z-axis. The origin of coordinates is at the center of the magnet. If the cylinder has uniform axial magnetization M, a.) determine U* (z) at points on the symmetry axis, both inside and outside the magnet, and b.) use the results of part a.) to find the magnetic induction Bz at points on the symmetry axis, both inside and outside the magnet.

A very long coaxial cylindrical cable is composed of an inner solid cylinder of radius R1 and an outer hollow cylinder of radius R2,{The space between inner and outer cylinders is empty}. An electrical current I runs through the inner cylindrical wire and returns through the outer cylindrical wire. (a) Write down the magnetic energy density function for both the inner and outer regions of the cable. (b) What is the energy per unit length L, for all regions (Both for inner and outer regions)? I did ask the same question last time, but I think the tutor was confused since the radius of the inner cylinder is R1, outer is R2. It's not R1 = 1R, R2 = 2R. Thank you
Consider a cylindrical coaxial cable. The center conductor is solid with radius of R, while the outer conductor is hollow with inner radius a and outer radius b. Both conductors have the same total current I (of uniform current density), moving in the opposite direction of each other. Find the magnitude of the magnetic field as a function of r (where r = 0 at the central axis) in the interval a is less than or equal to r which is less than b. I am unsure of how to start this problem and set up the correct equation.
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.
A circular loop having a radius of R and having a current of current I was put in a uniform magnetic field with a strength of B and it is also pointing out of the page. An angle of 30° was made by the loop with respect to the positive x axis in such a way that the loop’s right hemisphere is above the xy-plane, whereas the left hemisphere is below. This is illustrated in the figure attached. From the choices, determine the loop’s potential energy and the magnitude of the torque it experiences.
Two long wires, one of which has a semicircular bend of radius R and center P, are positioned as shown below. If both wires carry a current I, how far apart must their parallel sections be so that the total magnetic field at P is zero? Express a in terms of R. Does the current in the straight wire flow up or down? Explain. The infinite, straight wire shown below carries a current I1. The rectangular loop, whose long sides are parallel to the wire, carries a current I2. What are the magnitude and direction of the total magnetic force on the rectangular loop due to the magnetic field of the long wire?
