    The magnitude of the force on the wire is 0.33 N

    Explanation:

    Whenever a current-carrying electrical wire is placed during a field of force, a force is exerted on the wire. The formula for force depends on length (m), current (I) and magnetic field (B).

    The length vector depends on the direction of the present flow. The unit of force is Newtons (N), the unit of current is Ampere (A), the unit of length is the meter (m), and therefore the unit of the field of force is Tesla (T). The direction of the force vector will be found mistreatment the "right-hand rule".

    The magnitude of force = (current) * (magnetic field) * (length)

    = (6.04) * (0.219) * (0.252) = 0.33 N
