A mobile and effective electromagnet prototype with a large field-of-view for neonatal magnetic resonance imaging at 23 mT is presented. The efficient implementation succeeded by exploiting the use of steel plates as a housing system. This results in a design that ensures an optimum between large sample volumes, high homogeneity, high B₀ field, low power consumption, light weight, without the necessity of a dedicated water cooling system. Simulations and measurements are shown, which illustrate the functionality and quality of this imaging system. There are multiple paths to clinical and medical applications for such low cost devices.
