One practical example of how energy stored in a magnetic field is used in the real world is in magnetic resonance imaging (MRI) machines.
In an MRI scanner, strong magnetic fields are generated using superconducting magnets. When a patient is placed inside the MRI machine, the magnetic field temporarily affects the alignment of hydrogen nuclei in the body's tissues. The energy stored in the magnetic field allows for precise manipulation of these nuclei.
When radiofrequency pulses are applied, the nuclei are disturbed from their aligned state and then return to equilibrium. As they relax, they emit radio waves, which are detected by the machine. The MRI software processes these signals to create detailed images of the organs and tissues inside the body.
This application demonstrates how energy stored in magnetic fields is integral to non-invasive medical imaging, which is critical for diagnosis and treatment planning.
