This time, each magnet is now attracted to the iron plate, and don't see the other magnet on the other side of the plate, even though both of the North poles are facing each other! The diagram on the right shows what happens if you insert a superconductor between the magnets. Now, each magnet is repelled by the superconductor, and there is little or no attraction between the magnets themselves (one little field line did sneak around the superconducting plate, though).
Cardiac muscle (heart muscle) This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised.
There are three major types of muscle tissue: 1  Cardiac Muscle. 2  Cardiac muscle is so named because it is found in the heart. 3  Cells are joined to one another by intercalated discs which allow the synchronization of the heart beat. 4  Cardiac muscle is branched, striated muscle. 5  Skeletal Muscle.here are three major types of muscle tissue: 1  Cardiac Muscle. 2  Cardiac muscle is so named because it is found in the heart. 3  Cells are joined to one another by intercalated discs which allow the synchronization of the heart beat. 4  Cardiac muscle is branched, striated muscle. 5  Skeletal Muscle.
