An area round an object which is under the influence of the magnetic force exerted by the object.
The space permeated by the magnetic lines of force surrounding a permanent magnet or coil of wire carrying electric current.
The region surrounding a charged magnet where the presence of a magnetic force can be detected.
In the realm of magnetism, there exists a fascinating concept known as the three-dimensional magnetic field, which surrounds a magnet and encompasses the region where its force manifests. This expansive field represents the sphere of influence of the magnet, extending outward in all directions. During magnetic resonance imaging (MRI), a remarkable medical technique, the patient’s body is immersed within this force field, generated by a superconducting magnet. The permeation of the patient’s body by this powerful force field enables the acquisition of detailed images and invaluable diagnostic information, shedding light on the intricacies of human anatomy and aiding in the detection and understanding of various medical conditions. The captivating interplay between the magnet’s force field and the patient’s body forms the foundation of this non-invasive imaging modality, revolutionizing the field of medicine and contributing to improved patient care and diagnosis.
