Miniscule by comparison. Maybe even Micro-miniscule,
The level of magnetism in a magnetic bracelet an MRI is like the difference between a pea shooter and an artillery piece..................
About 15 years ago I had an accident while ice skating, and messed up some ligaments in my ankle. Extremely painful. Next day, while on crutches, visited the Mystery Spot near Santa Cruz, CA. Planned outing with extended family visiting and did not want to miss it. The Mystery Spot has magnetic anomalies there. Amazingly, much of the pain I was feeling went away.
I bought magnetic bandages for my ankle and wore them every day. Two weeks later my doctor was amazed at how quickly my ankle had healed. Maybe the magnets helped the blood flow in my leg.
