How do you make a compass without a magnet?
Magnetic compass. Modern compasses usually use a magnetized needle or dial inside a capsule completely filled with a liquid (lamp oil, mineral oil, white spirits, purified kerosene, or ethyl alcohol are common).
Can you make a compass with a needle and a leaf?
Here are two ways of making your own compass: If you have a sewing needle and a magnet you can magnetize the needle by running it down the magnet a few times. Find some stagnant water and set a leaf in it. Now set the pin down on the leaf, and the leaf will swing just like a compass.
How can a compass help you?
Compasses work so effortlessly because their design allows the magnet to respond freely to Earth's magnetic field. Earth itself is like a giant magnet that creates its own magnetic field. The north end of a compass is drawn to align with Earth's magnetic North Pole. Earth's magnetic field can change over time.
Does a compass have water in it?
Like all magnetic fields the Earth's magnetic field has two main poles, a north and south pole. These were a magnetized piece of metal floating in a bowl of water. The water provides the first frictionless pivot needed for making a working compass.
How do you make a circle with a compass?
A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth's built-in magnet. Since unlike poles attract, the thing your compass is being attracted to must be a magnetic south pole.
