And a mini magnetic compass.

or some material you can magnetize in the center plus a known magnet to check the polarity.

Battery? Be careful, you put DC direct over the coil.

When your battery is too strong the coil will heat up and eventually burn out. When the battery is too small, it will not last long. Work fast and not while in a measurement circuit.
