Hello,
In the Science paper I found the expression for magnetic Force (F) calculated from energy (W'), as it shown in the picture bellow:
Please could you help me with explanation, how the final expression for force F is derived after substituting W' in the first expression for force F. Instantaneous is mentioned in figure? Why lambda was used as a constant for integration (it is also a function of a variable i)? Just the variable i is added after integrating (di) and lambda is written like a constant?
Thanks and best regards
Ernest
