Magnetic Field. While MRI is considered to be a safe imaging technique, it is not without hazards. The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles. 2. structure, and the diborane-like PH. 5. structure predicted by quantum mechanical calculations. Phosphorus atoms are gold, hydrogen atoms are white.
