- Want to find the direction of force on a voice coil due to magnetic field
I want to understand the direction of force on the voice coil, if the conductor is straight line it is easy to find the force direction. In the case of the diagram i shown below, for the curved surfaces i should take tangential to the surface at every point. Am i correct? So for position 1 since ##I## and ##\vec B## are parallel, the force due to Pos1 will be 0. For Pos2 since Current and B are perpendicular the direction is to the right. For Pos3 it is little confusing, it is towards right (not completely). Does the direction of force change if the voice coil is aligned differently? I think it is the relative orientation between ##I## and ##\vec B## that matters?
