許多行星（如木衛三，水星，地球，木星和土星）和恆星（如太陽）具有內部磁場.對這些磁場的存在和變化的解釋對行星科學家和天體物理學家是一個巨大的挑戰.本文試圖總結行星和恆星的導電流體內部磁流體力學研究的新近發展和困難.一般由熱對流驅動的流動通過磁流體力學過程產生並維持在行星和恆星中的磁場.在行星中磁流體力學過程強烈地受到轉動，磁場和球幾何位型的綜合影響.其動力學的關鍵方面涉及科里奧利力和洛倫茲力間的相互作用.在太陽中其流線，即處于對流層的薄的剪切流層在太陽的磁流體力學過程中扮演了一個基本的角色，並由之產生了11年的太陽黑子周期.本文也給出了一個新的非線性三維太陽發電機模型Radio astronomers are now able to synthesize the response of a partially filled aperture of large diameter and thus to map variations in nebular brightness.
