A single loop of wire in the shape of a square with sides of
length l=25.0 cm is sitting in a uniform magnetic field of 1.30 T.
The field points out of the page, and the the loop is in the plane
of the page with sides parallel to the x and y axes.
(a) If a current of 3.70 A flows through the loop, what is the
magnitude of the magnetic force on a single side of the loop?...

A
rectangular loop with sides a and b (b> a) consists of a wire
whose resistance can be neglected and has a mass of self-inductance
L. The loop moves initially with speed of module v_0 along the
longest side and passes through a region with zero magnetic field
to another with uniform magnetic field of module B_0, perpendicular
to its plane. Therefore, for this turn, determine:
a) speed as a function of time.
b) the position as a function of...

A wire loop with 40 turns is formed into a square with sides of
length ss. The loop is in the presence of a 1.60 T uniform magnetic
field →B→ that points in the negative yy direction. The plane of
the loop is tilted off the x-axis by θ=15. If i=1.80 A of current
flows through the loop and the loop experiences a torque of
magnitude 0.0745 N⋅m, what are the lengths of the sides ss of the
square loop,...

A 4 x 10 cm rectangular loop of wire is situated on the x-y
plane with its corners located at coordinates (0, 0), (10,0), (10,
4) and (4,0) respectively. The loop has a current of 30 A flowing
in the counter-clockwise direction. Determine the magnetic field at
the centre of the loop.

1. A circular loop of wire has radius R and
carries a counter-clockwise current I. Find the magnetic field at a
height H above the center of loop.

A square loop and a rectangular loop are each made from the same
length of wire. Each loop contains a single turn, and carries the
same amount of current. The loops are placed in the same uniform
magnetic field. The long sides of the rectangle are four times as
long as its short sides. Determine the ratio of the maximum torque
on the square loop to the maximum torque on the rectangular loop.

In the figure, a rectangular loop of wire with length a
= 2.5 cm, width b = 1.7 cm, and resistance R =
0.28 mΩ is placed near an infinitely long wire carrying current
i = 5.6 A. The loop is then moved away from the wire at a
constant speed v = 3.1 mm/s. When the center of the loop
is at distance r = 3.4 cm, what are (a)
the magnitude of the magnetic flux through the loop...

Problem 9:
A rod AB with length L = 0.105 m is lying on a
rectangular conducting loop of zero resistance in a magnetic field
as shown in the figure. The magnetic field has a constant magnitude
B = 0.85 T. The rod is moving to the right with speed
v = 0.52 m/s. The resistance on AB is R = 120
