A lancet device ( 10 ) having an internal magnet ( 20 ) and the forces emanating therefrom driving and retracting a collar ( 30 ) and a lancet ( 60 ). The device has a steady state condition (SS) wherein the device is at rest and in equilibrium. The device can be armed and activated to puncture. Once puncturing has occurred the device returns to a steady state condition. A lancet method involves positioning both a magnet ( 20 ) and a member ( 30 ) capable of being affected thereby with a lancet ( 60 ) in communications with one of either the magnet or the member, positioning either the member ( 30 ) or the magnet ( 20 ) to an armed position wherein the magnetic forces from the magnetic affect the member, and releasing the one of either the member or the magnet from the armed position permitting movement between the member and magnet by at least, in part, the magnetic forces, resulting in the movement of the lancet from a withdrawn position to the piercing position.
