I'm sorry, but the question provided seems to be incomplete or unclear. It mentions "direct digestion" and then jumps to asking about magnetism without a clear connection. To provide a clear and concise answer, I would need a more complete question or context to work with.
If you have additional information or details related to the question, please provide them so I can assist you better. Feel free to ask a more specific question or provide more context for me to help you accurately.
