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

question 130

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, from A to E,as shown in the figure.It is placed in a uniform magnetic 0.75-T $\vec { B }$ field 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 $\vec { B }$ field direction is measured.What are the magnitude and direction of the magnetic force exerted on section AB of this wire?

• A)0.20 N perpendicular out of the page
• B)0.40 N perpendicular out of the page
• C)0.11 N perpendicular out of the page
• D)0.20 N perpendicular into the page
• E)0.11 N perpendicular into the page
