this metal wave helix demonstrates pulse propagation

5 inch diameter unit produces a +/-3mm controlled vibration on a string or ripple-tank dipper when driven by an external square-wave generator

illustrating how current direction and field together produce force

heating the bar until it no longer passes through the opening and contraction returns it
