A compass needle always points in the north direction because the north pole of the magnet attracts the earth's magnetic north pole due to the presence of the earth's magnetic field. Earth itself is considered to be a large magnet. Due to this reason, every magnet used in the earth usually rests in the direction of the north pole.
It is a device that is used for the purpose of navigation but it does not always point towards the true north. The earth's magnetic north pole and the earth's geographical north pole are not the same. They are both different.
Thus, the compass having the needle pointing in the northward direction always points towards the north even if it is used in the southern hemisphere.
Electricity is the essential need for everyday life.
Electricity problems are caused due to failures and errors in the electricity network, these might include man power error at the source, circuit failure, wires burn out etc. apart from these certain natural calamities also can harm the power supply, which include storms which harm the wires transmitting the electricity, heavy rain which causes damage to the electricity poles .
Solar flares and grid failures also lead to electricity failures.
