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.

In figure below, the magnetig flux through the circular loop of radius r = 1.8 m increases according to the relation ΦB = 5 t2 + 5t + 3, where ΦB is in Webers and t is in seconds. What is the magnitude and direction (clockwise or counterclockwise) of the induced current in the circular loop at t = 1.5 s if the loop has a total resistance of R = 12 Ω? (Choose clockwise direction as the positive and express the direction of the current by using plus or minus signs in the result, which must be in units of Amperes and include 2 digit after the decimal point. That means if you get a result of 9.22 and the direction of the current is clockwise, just type 9.22 or if you find the direction of the current to be counterclockwise, just type -9.22 in the answer box. Maximum of 5% of error is accepted in your answer.)
Imagine two concentric nested infinite solenoids having the same number of turns per unit length, but with radii R and 2R, respectively, and carrying currents I in opposite directions. Calculate the magnetic field a. in the region inside both solenoids, b. in the region between the solenoids (Hint: the answer is |Bvector| = μ0 * I * N / L), and c. in the region outside the solenoids. Assume that the thickness of current-carrying regions are negligible. Note that the magnetic field inside and outside an infinite solenoid with N turns of length L is Bvector = Bz * zhat, where Bz = 0 outside and Bz = μ0 * I * N / L inside its hollow interior.
