    Care to explain to me why the metal objects they are rifling through the bag aren’t flying into the MRI machine then?

    Turning off the Magnet
    Is the magnetic field turned on and off between patients?
    Resistive electromagnet scanners, in theory, can be turned on and off. However, it may take 30-60 minutes for their magnetic fields to stabilize after being off and hence they are generally left continuously on during daily operations. To save electricity, they are usually turned off or have their power levels reduced after hours.

    If you don’t understand how MRI machines work that’s fine, but please show your way out of the conversation and let people who want to have an actual discussion participate.

      Um. You proved me right and have therefore suggested for me that this was staged. Congratulations?

      The MRI magnet is ALWAYS on. This means no person is allowed to enter the MRI scan room without clearance and permission from a certified technologist. Metallic objects (such as fingernail clippers, pocket knives and even pens) can lead to serious bodily injury if brought within the magnetic field.

        Lol, you linked a different hospital’s rules regarding MRIs, which are that way because under normal circumstances it never shuts off. I linked you a page that shows that there are three types of MRIs, and one of them can in fact turn off its magnetic field. Now, I haven’t established if that’s the kind that they use in Al-Shifa, but it’s quite possible. At very least the fact that it’s off means there is no moving magnetic field and depending on where the magnet is, it may be totally possible to stash a bag there without negative consequences. Different machines use different magnetic strengths. The fact that the metal items in the bag aren’t being affected makes your theory not very compelling and seems to be proof that this is possible.
