Calculating Force in Electrodynamics

This lecture presents a detailed example of calculating force in an electromechanical actuator with a fixed magnet and a movable coil. The instructor explains the methodology step by step, analyzing the forces due to the magnet, the coil, and the mutual interaction. Through visual representations and mathematical derivations, the lecture demonstrates how the force is affected by the position of the components and the current flowing through the coil. The concept of mutual force is explored, emphasizing the importance of component positioning for optimal performance. The lecture concludes by highlighting the linear relationship between force and current in electromechanical actuators, discussing their advantages and limitations.
