The conducting wire wrapped around the compass is energized creating a magnetic field that counteracts the effects of the Earth's magnetic field and changes the direction of the compass needle.
on a compass it caused the compass to point to the magnet instead of magnetic north, I think that South will point to the magnet (if I remember correctly) You can get around this by using our patent which allows a magnetic radio speaker in a radio direction finder to sit directly next to a compass - by aligning the radio speaker to sit directly south of the compass it does not effect the accuracy.
One simple method is to use a compass.
Put the compass on the table and, with the wire near the compass, connect the wire between the positive and negative ends of the battery for a few seconds. What you will notice is that the compass needle swings. Initially, the compass will be pointing toward the Earth's north pole (whatever direction that is for you), as shown in the figure on the right. When you connect the wire to the battery, the compass needle swings because the needle is itself a small magnet with a north and south end. Being small, it is sensitive to small magnetic fields. Therefore, the compass is affected by the magnetic field created in the wire by the flow of electrons.
A lodestone is magnetized and thus produces a magnetic field around it. This can be detected by the deflection of a compass needle.
It could not be used because it attracts magnets and a compass is a specialist form of magnet, utilising the magnetic properties of the earth to give a reading. Compass housings are invariably made of brass, aluminium or plastic.

Iron reacts with oxygen and water to form rust. Not a good thing for a compass.
The first compass was invented around the year 1044. Modern liquid magnetic compasses stem from the mariners compass that was invented in Europe around 1190.
The compass was developed in China around 247 B.C.
The dry compass was invented around 1300.
the first compass was made in China around the Qing Dynasty's rule.
it would spin around and around.
The first compass was invented around 247 B.C. in China and by the eleventh century it was used for navigation. In medieval Europe around 1300 the dry compass was invented and was replaced by the liquid filled magnetic compass in the early twentieth century. A compass is a navigational instrument which is used for determining the direction related to the Earth's magnetic poles......by shaheer iqbal
There are three, The Golden Compass, The Subtle Knife, and The Amber Spyglass. They are known as the "His Dark Materials" series. There is also a book set two years after the series centered on Lyra that is called Lyra's Oxford and another book will be published as a sequel to that although there is no certain release date. There is also a prequel to the His Dark Materials series centered around the characters Lee Scoresby and Iorek Byrnison called Once Upon a Time in the North.
The magnetic compass was made in China the second century AD. The Norse seamen of around 900 AD had magnetite rock that they used as a magnetic compass.
The Jeep Compass is a very affordable vehicle to purchase. The MSRP for a new 2012 is $20,075. To purchase a 2011 Jeep Compass it will cost you around $16,495.
