Question

13. Long time ago, people on ships and boats solved the problem of finding out what direction they were sailing in and, perhaps even more importantly, what direction they needed to go to get back home. Before that time, this work was quite troublesome for them, but the invention of the compass changed all that.
The magnetic compass contains a magnetic element that aligns itself with the earth’s magnetic field. Think of the earth as a big magnet. It has two magnetic poles, oriented north and south that are very close to the geographic North and South Poles, making the work easier​
