Abstract
A heart is artificially contracted to pump blood an artificial device that employs electromagnetic force. That device includes electromagnetic coils attached to ribs of the animal and permanent magnets are placed adjacent the electromagnetic coils. When direct electric currents are applied to the electromagnetic coils the magnetic fields from the coils and the permanent magnets interact to repel permanent magnets which apply contraction force to the heart.
