What are air core resistive magnets characterized by?

Air core resistive magnets are characterized by their ability to produce a horizontally oriented magnetic field through the use of resistive coils. This design facilitates relatively straightforward alignment and an efficient way to manage the direction of the magnetic field, enhancing the imaging capabilities in MRI applications.

The ability to generate a horizontally oriented field is essential for appropriate anatomical positioning during imaging procedures and can significantly impact the resultant image quality.

Other aspects, such as the inability to turn off the magnetic field and very high field strengths exceeding 1 Tesla, do not align with the nature of air core resistive magnets. Generally, air core resistive magnets can be turned off, and their field strengths are typically less than those produced by superconducting magnets, which can achieve much higher values. Additionally, air core resistive magnets do not necessarily require permanent installation, as their resistive coils can be set up in a way that they are not permanently fixed, allowing for flexibility in deployment.
