In this study, as the first step to explicate the fundamental phenomena of Electromagnetic Casting (EMC), we provided an electromagnetic force generated by an electric source of 20 kW, 3 kHz and a electromagnetic coil with 18 turns to the molten aluminum. After confirming a stable meniscus in the electromagnetic mold, the bottom block was drawn in vertical direction. And a cylindrical aluminum ingot which size can be varied from 30 to 60 mm in diameter was fabricated. This ingot has the luster and the smooth surface typical for EM cast. Microstructural observation showed that the secondary dendrite arm spacing was 6 to 8 μm.
