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.
An electric motor uses electrical energy to produce mechanical energy, very typically through the interaction of magnetic fields and current-carrying conductors. An electric motor is all about magnets and magnetism: A motor uses magnets to create motion. The fundamental law of all magnets: Opposites attract and likes repel. So if you have two bar magnets with their ends marked north and south, then the north end of one magnet will attract the south end of the other.
