Two circular loops of current parallel to the z = 0 plane are arranged to form a Helmholtz coil. The center of one loop is at (0,0,0) m, and the center of the other loop is at (0,0,4) m. The radius of each loop is 2 m, and each loop carries a current of 5 A in the abφ direction. Find the magnetic field at (a) (0,0,0) and

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · 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, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
