Magnetic resonance imaging (MRI) is one of the most useful and rapidly growing medical imaging
tools. It non-invasively produces two-dimensional and three-dimensional images of the body that
provide important medical information with none of the hazards of x-rays. MRI is based on an effect
called nuclear magnetic resonance (NMR) in which an externally applied magnetic field interacts with
the magnetic fields of nuclei of certain atoms, particularly those of hydrogen (protons). The external
magnetic field is created by a large coil. This field interacts with the hydrogen atoms in the patient's
body to form images.
a) To see why an MRI utilizes iron to increase the magnetic field created by a coil, calculate the
current needed in a 400-loop-per-meter circular coil 0.665 m in radius to create a 1.1 T field (typical of
an MRI instrument) at its center with no iron present.

Introducing ferromagnetic materials inside coils greatly increases the magntic field inside the coil for
