I am new to this forum, and this is my first post. Please bear with me if my query has any inaccuracies.
In the attached figure, a coil is wrapped around the central arm of a flat H-shaped thin metallic plate (such as iron). DC current flows through the coil and magnetizes the arm. At the same time, DC current also flows from another source through the plate as shown in the figure. Within the central arm, the directions of flow of the magnetic flux and current are perpendicular to each other.
If B is the magnetic flux density, L is the length along which the current I flows through the arm, does the plate experience a force F according to the equation F = B I L ?
I am asking this question because generally when we read about force acting on a current carrying conductor in a magnetic field, the magnetic field is understood to be external to the conductor. In this case, it is not. Hence, the query.
