MRI

• The Magnetic Resonance Imaging (MRI) scanner uses a powerful electromagnet cooled in liquid helium. The MRI scanner uses the strong magnetic field to create detailed internal images of the body.
  
  

TMS

• Transcranial Magnetic Stimulation (TMS) is a technique for stimulating the brain. An electromagnet sends a pulsed magnetic field to the patient's head. In some people, it appears to alleviate depression.
  
  

SQUID

• Superconducting Quantum Interference Devices (SQUIDs) are electromagnets able to sense tiny electrical changes. They can be used to map brain activity without surgery.
  
  

Surgery

• Surgeons sometimes use electromagnetic tools to remove metal fragments from patients. The magnets attract bits of metal that would otherwise be difficult to find or grasp.
  
  

Patient Rooms

• Designers have proposed using a system of ceiling-mounted arms to organize monitoring equipment in patient rooms. Electromagnetic brakes in the arms serve to hold equipment in place.
