Compass

• navigation device whose magnetized needle usually points north
• map the invisible field around a magnet
• angle between geographic north and the north to which a compass needle points
• area of magnetic force around a magnet

If you allow a magnet to swing freely, it will align itself to the

• east and west
• north and south
• diagonally

You can increase the strength of an electromagnet by

• changing the position of the compass
• adjusting the magnetic declination
• using a stronger ferromagnetic material for the core
• reversing the current
