Question

A current-carrying wire is in the shape of a square of edge
length 5.0 cm. The square lies in the *z* = 0 plane. The
wire carries a current of 2.1 A.

(a) What is the magnitude of the torque on the wire if there is
a uniform magnetic field of magnitude 0.28 T in the +*z*
direction?

(b) What is the magnitude of the torque if the field is in the
+*x* direction?

Answer #1

Area, A = 5.0*5.0 cm^2 = 25.0*10^-4 m^2 (k-direction)

I = 2.1 A (given)

M = IA = 2.1*25.0*10^-4 = 5.25*10^-3 Am^2 (k-direction)

**Part
A)**

B = 0.28 T (k-direction)

Torque, T = M(k-direction) x B(k-direction)

**Magnitude of
torque on the wire, T = 0**

(Since, Vector Product between two vectors in same direction is Zero)

**Part
B)**

B = 0.28 T (x-direction)

Torque, T = M(k-direction) x B(x-direction) = 5.25*10^-3 Am^2 (k-direction) x 0.28 T (x-direction)

**Magnitude of Torque, T = 1.47*10^-3
Nm**

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
square loop of side 4 cm, carrying a current of 5.2 A, is placed

A square current loop 4.6 cm on each side carries a 510 mA
current. The loop is in a 1.5 T uniform magnetic field. The axis of
the loop, perpendicular to the plane of the loop, is 30∘ away from
the field direction.

A square loop of wire, of side length 9.5 m, is placed on the
edge of a magnetic field of strength 3 T into the page. This field
can be described as a section of the Cartesian plane with x<0
(everywhere x is negative) and the loop is oriented so that it is
in this plane with its right edge at x=0 (it starts entirely within
the magnetic field).
The wire loop is then pulled in the +x direction (out...

A single loop of wire of radius 12 cm lies on the x-y plane
(imaging it lying on your page of paper) and carries a current of
1.00 A in the clockwise direction . At the same time, a long
straight wire that just touches the rim at the edge of the wire
loop carries a 0.808-amp current in the +z direction ("out of the
page"). Find the magnetic field at the center of the wire loop.
Reminder: the loop...

A 50 cm × 85 cm rectangular loop of wire is located in a region
of uniform magnetic field with a magnitude of B0=3.32
