SUMMARY
The force exerted by an MRI machine on a small object, such as a nail, can be estimated at approximately 3N/cm³ for iron or steel nails, given a magnetic field strength of 1-2 Tesla. This results in an acceleration of around 45g, where g represents the gravitational acceleration on Earth. The calculations assume an inhomogeneous magnetic field with a typical length scale of 1 meter, which is crucial for determining the force on the object.
