The magnetic force acting on a straight wire carrying current I of length
L in a uniform magnetic field B is given by
F = IL x B,
where L has length L and is pointing in the direction of the current.

(b) The torque with respect to a pivot point is defined by the cross
product of the separation vector i which is oriented from the pivot
point to the point where the force acts and the force,
チ=チxF.
Find the torque acting on this loop with respect to the origin as
the pivot point.
The magnetic dipole moment of a current-carrying loop of wire is in the positive z direction. If a uniform magnetic field is in the positive x direction the magnetic torque on the loop is: (0 , in the positive y direction, in the negative y direction, in the positive z direction, in the negative z direction.)
The armature (slender rod) AB has a mass of 0.20 kg and can pivot about the
pin at A. Movement is controlled by the electromagnet E, which exerts a
horizontal attractive force on the armature at B of FB = (0.20 (10–3) l 2) N,
Part A
where l in meters is the gap between the armature and the magnet at any instant.
(Figure 1)
If the armature lies in the horizontal plane, and is originally at rest, determine the speed of the contact at B the instant l = 0.01 m. Originally l = 0.02 m.
