You have a square loop with each side of length 'a' and a circular loop with radius 'a'. Both of these loopslie in the x-y-plane, where there is a uniform magnetic field B pointing at some angle 0 with respect to thepositive z-direction. Each loop has the same number of coils and carries the same current, in the samedirection. Therefore, the ratio of magnetic moments (u) in the loops, [square] / [circular] =O 1/ TO T 14O 4/ T

Please answer with complete solution.A beam of electrons (of charge −e and mass me) is shot into a region of uniformmagnetic field with a speed of 35 m/s. They exit the region of uniform magnetic field opposite the direction they had entered. How strong must the magnetic field be such that each electron stayed in the region for a total of 70 ms? Answer should be in me/qe unit.
Suppose that we observe that protons produced by an accelerator travel in a circular path of radius 8 cm in a uniform magnetic field whose magnitude is 3 T. What is the speed of these protons? Give your answer in units of 106 m/s.
A conducting rod is free to move along 2 parallel conducting rails. On one end a resistor, R, connects the two rails which forms a circuit. The rails are oriented along the y axis of a coordinate system. There is a constant magnetic B aligned with the z axis making it perpendicular to the plane of the rails and rod. If the rod is given an initial velocity of vo, and hence a kinetic energy of m*vo2 /2, mathematically demonstrate that as the rod rounds to a stop in an infinite time the power lost in the resistor as heat is equal to the initial kinetic energy.
A certain superconducting magnet in the form of a solenoid of length 0.30 m can generate a magnetic field of 10.0 T in its core when its coils carry a current of 80 A. The windings, made of a niobium-titanium alloy, must be cooled to 4.2 K. Find the number of turns in the solenoid. turns
You have a square loop with each side of length 'a' and a circular loop with radius 'a'. Both of these loops lie in the x-y-plane, where there is a uniform magnetic field B pointing at some angle θ with respect to the positive z-direction. Each loop has the same number of coils and carries the same current, in the same direction. Therefore, the ratio of magnetic moments (μ) in the loops, [square] / [circular]
Time left 0:47:22 As shown, a single loop (resistance R, width W, and length L) moves to the right at a constant speed of v = 5 m/s toward a region (indicated by the shaded area) of a uniform magnetic field directed into the page, of magnitude B = 2.9 T. Just as the loop passes a distance x through B, the force (in N) on the right side L must be: (Take R = 3 0, W= 25 cm, and length L= 45 cm] of W. OB 2.84 to the left-

Determine the torque acting on the rectangular loop of height l and width w in a constant external magnetic field B~ shown below with angle θ between the area vector and theexternal magnetic field. Show that the torque can be written as τ = m × B, where m = Ia is called magnetic dipole moment, I is the current in the loop, and a = wln is area vector for the area bounded by the loop. For this problem, take B = Bx and the sides of length l to be parallel and n perpendicular to the z-axis.
In Fig. 2, an electron with an initial kinetic energy of 5.0 keV enters region 1 at time t= 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.010 T. The electron goes through a half circle and then exits region 1, headed toward region 2 across a gap of 25.0 cm. There is an electric potential diference AV= 2000 V across the gap, with a polarity such that the electron's speed increases uniformly as it traverses the gap. Region 2 contains a uniform magnetic field directed out of the page, with magnitude 0.020 T. The elctron goes through a half circle and then leaves region 2. At what time t does it leave?
