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.
But if you put a north pole and a south pole together, the magnets will stick together because the north and south poles attract each other. Just like protons and electronsâopposites attract in magnets. Magnetic fields can be used to make electricity. The properties of magnets are used to make electricity. Moving magnetic fields pull and push electrons. Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.
