To determine the order of electromagnets from weakest to strongest magnetic force, we would typically need more information about each electromagnet's specifications, such as the amount of current flowing through them, the number of coils, or the type of core material used.
Since no additional information about K, J, and L is provided, I cannot definitively specify the correct order. However, if you have any details about the strength or parameters of each electromagnet, I can help you analyze that data to determine the correct order.
