    3.4 The Brain Spinal Cord Introductory Psychology

    In magnetic resonance imaging (MRI), a person is placed inside a machine that generates a strong magnetic field. The magnetic field causes the hydrogen atoms in the bodys cells to move. When the magnetic field is turned off, the hydrogen atoms emit electromagnetic signals as they return to their original positions.

    MR magnet types Questions and Answers in MRI

    There seem to be many different MRI magnets and designs. Can you explain? Over 90% of scanners world wide are of the closed bore cylindrical design and generate their fields by passing current through a solenoid kept at superconducting temperatures. Open bore magnets contain an air gap between two magnetic poles. Magnetic field created

    Electromagnet

    An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. and the remanence contributes to the motor's losses.
