A heart (10) is artificially contracted to pump blood using an artificial device (14) that employs electromagnetic force. That device includes electromagnetic coils (35, 37) attached to ribs (42) of the animal and permanent magnets (28, 30) are placed adjacent the electromagnetic coils. Wh en direct electric currents are applied to the electromagnetic coils the magnet ic fields from the coils and the permanent magnets interact to repel permanent magnets which apply contraction force to the heart.
