Question
Since F=ilB (i=current)(l=length)(B magnetic force) would make wire 3 experience largest F ? ans C
is E correct because if the magnetic field B is in same direction of v then F=0
Repeat Multiple-choice question 16, except assume that the uniform magnetic field could be pointing in any direction. Which wire segment experiences the largest net force? (A) 1 (B)2 (C)3 (D) All experience the same net force. (E) The answer depends on the direction of the magnetic field. 32-5 The Magnetic Force on a Current-Carrying Wire 16. Figure 32-3 0 shows several wire segments that carry equal currents from a to b. The wires are in a uniform magnetic field directed into the page. Which wire segment experiences the largest net force? (A) 1 (B) 2 (C) 3 (D) All experience the same net force. (E) The question cannot be answered without additional information.Explanation / Answer
Force on a current carrying conductor placed in magnetic field is given by:
F = i*L*B*sin@
Here @ is the angle between i,L,B. which is 900 in this case.
since i and B is same for all the three segments.so
force directly proportional to length.
Length of third wire segment is large as compare to other two.
so third segment will experience largest force. ans(c)
