Using a magnet, string and needle you can create a crude but workable compass.
Method
Get a needle or a very small nail and a bar magnet. Also get some thread or a bowl of water and two tiny pieces of cork.
Hold the needle in one hand and the magnet in the other.
Put the North end of the magnet against the needle in the middle and rub it towards and off the point.
Lift the magnet up and away from the needle and place it in the middle again.
Repeat rubbing the North end of the magnet against one half of the needle 20 times or so.
Flip the magnet over so you are using the South end and rub it from the middle to the 'eye' end of the needle 20 times.
You have magnetized the needle just like a compass needle.
Hanging Compass
Tie one end of a length of thread to a stick and the other end to the middle of the needle.
Balance is important
Let the needle hang freely and slide the thread to a point on the needle where it balances level.
Lower the needle into a wide-mouthed jar and lay the stick across the opening to prevent wind interference. Watch which way your compass needle turns. It should always settle to the same direction.

How could you use a bar magnet to find your way out the forest?
I would think the usual reason of getting lost is not following a straight path (going in circles). Human tends to favorite one side (because of inner ear imbalance), so the walking path is curved, and eventually you are back to the starting point. A compass will have set a more-or-less straight course. How to construct a compass with a bar magnet? I can think of two ways. You can tie the magnet to a string and let it settle with the magnet at the bottom of the string. The alternative is to find a puddle every so often, drop the bar magnet in the water, and let it show the way (if the magnet floats; it will be better if you can find a container to put water in and bring it with you).
