What was the purpose when the magnetic compass was first invented?A.Divination.B.Navi
Compass An instrument containing a magnetized pointer which shows the direction of magnetic north and bearings from it Walkers should be equipped with a map and compass A magnetic compass Crewe was ideally placed on the rail network, with connections running to all points of the compass Compasses ...
Amagnetic compassis a tool that fundamentally allows for the determination of a reference point or region on Earth corresponding to magnetic north. This is slightly different from true north, but with the varying correction factors required at different points around the globe now known, a good ma...
is a measure of thestrength of the magnetic field. Specifically, 1 Gauss is equivalent to 1 magnetic field line within 1 square centimeter.Also, the direction of the tangent to the field line is the direction of the magnetic field at that point and is the direction a compass would point....
