Problem 2. A wire with a length of 40 cm is placed in an electromagnetic field with a magnitude of magnetic induction 30 ut. Determine the magnitude of the current flowing
through the wire if the maximum magnetic force acting on the wire is 0.3 kN.
Given:
Looking for:
Solution:

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].
