3. Rectangular current loop A current I flows in a square current loop of wire placed on the ry plane and centered about the origin. The lengths of the two sides are a and b (a) Find the magnetic field at any location (0,0, z) on the z-axis. b) For z a, b, what does your expression simplify to?

A rectangular loop of wire has a length 2a in the x direction and a width 2b in the y direction. The loop lies in the z = 0 plane and is centered at the origin. Assuming that the loop carries a current of I Amps counterclockwise, as viewed from the positive z axis, find the magnetic field vector H at the center of the loop. Hint: Consider how the contributions from opposite sides of the rectangle compare, to save...
3. (a) A square loop of wire lies in the ry plane and is centred at the origin. Two segments are parallel to the axis and are at y = ±R. The other two segments are parallel to the y axis and are at z-th. The loop carries a steady current lo. What is the magnetic field at the origin? (b) The square loop of part (a) is replaced by a hexagon: the distance from the origin to the nearest...
A rectangular loop of wire that is 58 cm wide and 12 cm long is placed in a region where the magnetic field is B = 1.1 T. Suppose the wire loop lies in the x–y plane and that the magnetic field makes an angle of 70° with the z axis. Find the magnitude of the magnetic flux.
3) A square wire with current in it, wrapped once, is placed in the x-y plane. It's sides have a length of 1.8 m and the magnetic moment produced by it is 6 A m2 in the +z direction. The square wire is then reshaped, using all the wire from the square, into a circle with the same current as the square. The circle is then placed into the x-y plane (first quadrant) such that it's magnetic moment is also...
Calculate the net force of the rectangular current loop (4mx6m) on the square current loop (2mx2m). Both are centered at the origin in the z = 0 plane. The outer loop has a 1A current flowing clockwise and the inner loop has a 2A current flowing counterclockwise.
4. (a) A long straight wire carrying a current is placed near
a current-carrying rectangular loop. Describe how, and why, the
loop would move as a result of the magnetic forces from the long
wire. The current in the loop is counterclockwise.
(b) Suppose that you were to put in a different
loop below the long wire (and still in the plane of the page).
Draw the shape of a loop that would...

A wire loop with 7070 turns is formed into a square with sides of length ss. The loop is in the presence of a 1.60 T1.60 T uniform magnetic field →BB→ that points in the negative yy direction. The plane of the loop is tilted off the x-axisx-axis by θ=15∘θ=15∘.
