A long wire carrying a 6.20 A current reverses direction by means of two right-a

Question

A long wire carrying a 6.20 A current reverses direction by means of two right-angle bends, as shown in the figure (Figure 1) . The part of the wire where the bend occurs is in a magnetic field of 0.666 T confined to the circular region of diameter 75 cm , as shown. Assume that I= 6.20 A and d=44.5 cm .

Problem 20.31 Part A A long wire carrying a 6.20 A current reverses direction by means of two right-angle bends, as shown in the figure (Figure 1). The part of the wire where the bend occurs is in a magnetic field of 0.666 T confined to the circular region of diameter 75 cm , as shown. Assume that I= 6.20 A and d=44.5 cm Find the direction of the net force that the magnetic field exerts on this wire. The force is directed to the right. The force is directed to the left The force is directed into the page. The force is directed out of the page.

Explanation / Answer

magnetic field is out of the page ,current direction is downward so the magnitude of force will be toward left (by flemimg left hand rule)

The force is directed towards left

Magnitude=id*B=6.2*0.445*0.666=1.8375 N
