What can be said about the relative direction of the contributions due to the entire segments KL, LM, and MN to Bโ net at point P? What can be said about the relative direction of the contributions due to the entire segments KL, LM, and MN to at point P? The magnetic fields due to KL and MN have the same direction; the magnetic field due to LM has the opposite direction. The three magnetic fields have different directions. All three magnetic fields have the same direction.

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r ร f) ยท n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, โ5, 4] n, r = [โ3, 5, 2] m, and n = [6, 5, โ7].
