How does a compass work simple explanation?
A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet. (You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end.)Jul 28, 2010.
Where is the magnetic compass most effective?
It’s only on the equator that a typical compass will provide the most accurate reading about which direction is north and which direction is south, Jordan said. That’s because at the equator, all of the planet’s magnetic field lines are horizontal and parallel to Earth’s surface, he explained.

What is difference between true north and magnetic north?
True north is a fixed point on the globe. Magnetic north is the direction that a compass needle points to as it aligns with the Earth’s magnetic field. What is interesting is that the magnetic North Pole shifts and changes over time in response to changes in the Earth’s magnetic core. It is not a fixed point.
