A Wire in the Shape of an "M" Lies in the Plane

question 120

Multiple Choice

A wire in the shape of an "M" lies in the plane of the paper. It carries a current of 2.0 A, flowing from A to E, as shown in the figure. It is placed in a uniform magnetic field of 0.75 T in the same
Plane, directed as shown on the right side of the figure. The figure indicates the dimensions of the
Wire. Note that AB is parallel to DE and to the baseline from which the magnetic field direction is
Measured. What are the magnitude and direction of the force acting on section AB of this wire?

• A) \(0.11 \mathrm {~N}\) perpendicular out of the page
• B) \(0.11 \mathrm {~N}\) perpendicular into the page
• C) \(0.20 \mathrm {~N}\) perpendicular out of the page
• D) \(0.40 \mathrm {~N}\) perpendicular out of the page
• E) \(0.20 \mathrm {~N}\) perpendicular into the page
