Answer:
<em>Magnetic Field</em>
Explanation:
The outer core of the Earth possesses molten iron. This core gives rise to convectional currents. The movement of the convectional currents gives rise to the electric currents which make up the magnetic field of the Earth. The magnetic field of the Earth is also known as the Earth's magnetosphere. This is the area which comprises of the magnetic field of the Earth caused due to the movement of ions inside the core of the Earth.

One of the most general forms of discomfort or pain one feels at the time of strenous work out is a burning sensation in the muscles or lungs, which goes away after some time, that is, after stopping the activity. This is a result of an accumulation of lactic acid.
Lactic acid is a by-product of the procedure the body goes through when it requires to generate energy more briskly that it does usually, like when one exercises.
The muscles functioning generally produce energy aerobically, that is, by using oxygen, however, when one push himself or herself at the time of workout and enough oxygen is not accessible, then these muscles start producing energy anaerobically, resulting in production of lactic acid as a by-product and ultimately causing burning sensation.
