What is the force per meter on a straight wire carrying 5.0 A when it is placed in a magnetic field of 0.020 T so that the wire makes an angle of 27° with respect to the magnetic field lines.
A)0.022 N/m
B)0.045 N/m
C)0.17 N/m
D)0.26 N/m

Quizplus · Accepted Answer

The force per meter (f) on a straight wire carrying current (I) in a magnetic field (B) is given by the formula f = IBLsin(θ), where θ is the angle between the wire and the magnetic field. Substituting the given values: f = 5.0 A * 0.020 T * sin(27°) = 0.045 N/m.
