Niken Information
Niken TipsAlthough we cannot see or feel them, magnetic fields are all around us. Any moving electric charge produces both electric and magnetic fields. Just like an electric field, a magnetic field exerts a force on other charges as well, so long as they are moving in a direction that is not parallel to the field itself. Electric current flowing through a wire produces a predictable magnetic field. The direction of the field can be determined by using what is commonly known as the 'right hand rule'. By imagining that you are grasping the wire with your right hand and pointing your thumb along the wire in the same direction that the current is moving, the way in which your fingers curl is the same way the resulting magnetic field is oriented. From this, its clear that magnetic fields resulting from a current carrying wire occur in a circular form, spinning around the wire. The field is strongest close to the wire, and diminishes with distance. Niken AdviceAnother way to define magnetic fields is by the amount of force they will exert on a given charge. The force is determined using the equation F = qvB, where F is the force in newtons, q is the charge the force is acting on measured in coulombs, v is the velocity of charge q in meters per second, and B is the magnetic density of the field in teslas. In the meantime, while research continues unfortunately most athletes are forced to continue using the methods of heat and ice to help promote faster healing for their injuries. Once the research is developed further, we can expect that it will be widely available to all athletes, as well as non-athletes alike. Niken Facts
