5. given a square coil, rectangular coil
same length of wire
n = 1
for rectangel
width = w
l = 2.4w
so the ratio of maximum torque will be ratio of the areas
hence
Ts/Tr = As/Ar
As = a^2
Ar = lw = 2.4w^2
now, 4a = L
2l + 2w = 6.8w = L
hence
Ts/Tr = L^2*(6.8^2)/16 * 2.4*L^2 = 1.2041666

A square coil and a rectangular coil are each made from the same length of wire. Each contains a single turn. The long side of the rectangle is 1.5 times the short side. Find the ratio (τsquare/τrectangle) of the maximum torques that these coils experience in the same magnetic field when they contain the same current.
A square coil and a rectangular coil are each made from the same length of wire. Each contains a single turn. The long sides of the rectangle are twice as long as the short sides. Find the ratio τsquare /τrectangle of the maximum torques that these coils experience in the same magnetic field when they contain the same current.
You use two wires of the same length to make a single turn square coil and a single turn rectangular coil. For the rectangular coil, the long side is 3 times the length of the short side. If these two coils have the same current and are placed in the same magnetic field, determine the ratio τmax,s/τmax,r of the maximum torques that the coils experience.
You have a wire of length L = 0.8 m for making a square coil of a dc motor. The current in the coil is I = 2.1 A, and the magnetic field of the motor has a magnitude of B = 0.18 T. Find the maximum torque exerted on the coil when the wire is used to make (a) a single-turn square coil and (b) a two-turn square coil.
Figure (a) shows a length of wire carrying a current and bent into a circular coil of one turn. In figure (b) the same length of wire has been bent more sharply, to give a coil of two turns, each of half the original radius (a) If Ba and Bo are the magnitudes of the magnetic fields at the centers of the two coils, what is the ratio BWB? (b) what is the ratio of the dipole moments, μαυα, of...
