Study findings do not support routine use of oxygen therapy in all patients with heart attack symptoms Oxygen is a blood vessel constrictor or vasoconstrictor. As blood vessels are constricted, circulation in the peripheral blood vessels is significantly reduced, an effect that was previously thought to increase the risk of stroke.
Making the world better, one answer at a time. The magnets in speakers work to absorb the sounds running through the coils. Think of it as a big dust collector and the dust in the sound coming through.n speakers magnet is fixed and the conductor (in the form of a coil is fixed to the back of the diaphragm) is allowed to move freely. As the coil is fixed to the diaphragm the movements of the coil is reciprocated by the movements of the diaphragm.
Sound is actually an energy wave of molecules that create a vibration. Sound can travel through and bend around many objects, including water. Check out how sound works: 1  When an object moves it creates a vibration. 2  Vibrations move air particles around. 3  These moving particles are constantly bumping into each other. 4  Our ears can pick up these particle-vibrations as sound. 5  Fast moving particles create a high sound, while slow ones are low-sounding.
