where is earth's magnetic north pole?
Answer:
The north magnetic pole is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down)
Explanation:
There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.
The Earth's magnetic pole is situated at west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W.
What is the Earth's magnetic pole?The generation of the Earth's magnetic field occurs deep within the Earth's interior, in a layer which is known as the outer core to be more precise. Here, the convective energy from the slow-moving molten iron is converted to the electrical and magnetic energies.
The north magnetic pole of the Earth moves over time according to the magnetic changes and flux lobe elongation in the Earth's outer core. In the year 2001, it was determined by the Geological Survey of Canada to lie west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W. It was situated at 83°06′N 117°48′W in 2005.

products?
Answer:
so that our body won't contain all the bad waste and allow all the good nutrients to help out our body.
The body of an organism utilizes the nutrient and the energy derived from the food.
The digestive system of an organism is accountable for breaking, digesting, absorbing and assimilating food.
The cells in our body perform biochemical reactions in which some of the substances are harmful or fatal to the body cells if gets stashed.
The method by which the excrement from the body is thrown out is called excretion.
So, for the appropriate functioning and for the cell to sustain discarding of wastes is required.
