Which best explains how Selena can correct her error?
She can change the magnets so like poles are facing
each other.
She can change the arrows so they show current
traveling in opposite directions on the sides of the loop.
She can change the arrows so they show the magnetic
field reversing direction between the magnets.
She can change the magnetic poles so they are both on
one side of the loop.

Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? a)\vec ein the +xdirection,\vec bin the +ydirection. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction b)\vec ein the -y direction,\vec bin the +x choose+ x direction- x direction+ y direction- y direction+ z direction- z direction c)\vec ein the +z direction,\vec bin the -x direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction d)\vec ein the +y direction,\vec bin the -z direction. choose+ x direction- x direction+ y direction- y direction+ z direction- z direction
