I can interpret this as it's somewhat of all of those, due to the fact that for one thing think of the earth it's a spinning ball of liquid iron, nickel due to one law stating hot liquid metal spinning around creates magnetic fields, ferro magnetic metals are ones such as magnetite which is a natural magnet, it can be found in nature theres a region in the gobi desert that will make a compass needle dance since its surrounded by magnetic rock, ferro magnetic atoms like iron, nickel are great at being and creating magnetic fields due to their ability to change from non magnetic to magnetic quickly and with different ways from inducing as in electromagnetic coils forcing atoms spinning differently to spin the same direction or changing the north south alignment. you can take a iron pipe and hit it with a hammer and after enough wacks the atomic structure will be disrupted and all the atoms line up in tightly compacted lines like grains in wood creating a stronger magnetic pull than if it was just a iron pipe. I hope that helps I like metaphors for understanding those kinds of concepts I hope that's helped.
Answer and explanation;
The use of coal has steadily increased from 1800 to 2004. Burning coal was the leading cause of global fossil carbon emissions. Petroleum use rose quickly after 1950.
Coal can be defined as a sedimentary rock that burns. It was formed by the decomposition of plant matter, and it is a complex substance that can be found in many forms.
Energy consumption patterns have changed over the history of our country as we developed new energy sources and as our uses of energy changed. Coal became dominant in the late 19th century before being overtaken by petroleum products in the middle of the last century, a time when natural gas usage also rose quickly.
