The human body is mostly water. Water molecules (H2O) contain hydrogen nuclei (protons), which become aligned in a magnetic field. An MRI scanner applies a very strong magnetic field (about 0.2 to 3 teslas, or roughly a thousand times the strength of a typical fridge magnet), which aligns...
What Kind of Equipment Is Used in an MRI? A typical MRI machine is a large tube with a hole at both ends. A magnet surrounds the tube. You lie on a table that slides all the way into the tube. In a short-bore system, you are not totally inside the MRI machine. Only the part ...

An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the ma...
What Does an MRI Scanner Look Like & How Does it Work? The MRI scanner looks like a tube which is surrounded by a giant circular magnet. A moveable bed is present on which the patient is made to lie down and this table then passes into the magnet. A strong magnetic field is produced...
What is an MRI? What is angular momentum? What is inversion in meteorology? What is nuclear disintegration? What do Rossby waves do? What are tidal current turbines? What is a superconductor? What is resistivity in geophysics? What are Polar Easterlies?
MRI is a very safe procedure. The strong magnetic field itself does not hurt people, unless they have certain types of metal implanted in their body. The magnetic field can cause certain types of metal to move, which could potentially cause an injury. ...
How is the magnetic field of an electromagnet controlled? When does a magnet lose its magnetism? How does a magnetic field create electricity? What does the magnetism in an MRI help accomplish? How does an electric field produce a magnetic field?

The MRI machine uses a powerful magnet. Do not enter the MRI room with anything metal. Metal can cause serious injury from the magnet. Tell the healthcare provider if you have any metal in or on your body. Electromyography (EMG) is done to test your muscles and the nerves that control ...
