/sci/, physics 102 questions.
PLEASE FOR THE LOVE OF GOD DO NOT TELL ME THE ANSWER UP FRONT.
that doesn't help.
anyway;

first one)
15Amps is directed along the positive x-axis and perpendicular to a magnetic field. A magnetic force per unit length of .12N/m acts on the conductor in the negative y-direction. Calculate the magnitude and direction of the magnetic field in the region through which the current passes.

feels like there's some really easy equation to solve this, except i cannot locate one in my textbook

second one)
much harder to describe, see pic
