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.
Best Answer: The magnet is part of the 'motor' of the sub. The coil inside the magnet has alternating current running through it. The coil acts as an electromagnet and pulls itself up or pushes itself down moving the cone of the speaker.o the speaker cone will have something to be attracted to or push against, producing vibration which is then heard by your ears as sound. To a point anyway, the bigger the magnet the better the sound. There is a coil of wire at the smallest part of the speaker that acts as an electromagnet.
