Magnetic Resonance is a popular imaging modality for research and diagnostic purposes. With the increased usage of smaller localized insert coils needed to provide the resolutions required to image smaller sample sizes, the safety with regards to the Lorentz forces has been investigated. These insert coils are made to be readily interchanged in a MR magnet, and are not often motion stabilized inside the magnet's bore. With the large magnetic fields produced by an MR magnet, the Lorentz forces and torques on an insert coil may become quite large, especially during coil failure. In this study the safety of an insert coil will be investigated under catastrophic electrical failures and coil mis-positions to determine if the Lorentz forces and torques on the insert coil will be large enough to cause coil motion.
