Question
Consider the long, straight, current-carrying wires shown below. One wire carries a current of 9.9 A in the + y direction; the other wire carries a current of 4.5 A in the positive x direction.
(a) Conceptually: At which of the two labelled points do you expect the magnitude of the net magnetic field to be greater?
---Select one--- A B same at A & B
(b) Calculate: What is the net magnetic field at each of these points?
(Do your answers match your predictions from part a?)
at point A:
size: in T
dir: ---Select one--- +x dir -x dir +y dir -y dir into page out of page N/A - field is zero
at point B:
size: in T
dir: ---Select in---+x dir -x dir +y dir -y dir into page out of page N/A - field is zero
(c) What force would be felt by a proton placed at point B at rest?
size: in N
dir: ---Select one--- +x dir -x dir +y dir -y dir into page out of page N/A - force is zero
(d) What force would be felt by a proton when passing through point A at 25 m/s in the +y dir?
size: in N
dir: ---Select one--- +x dir -x dir +y dir -y dir into page out of page N/A - force is zero
