COMPASS TRAINING WHEEL Φ40x8mm PLASTIC
The price does not include VAT.
New device with magnetic pole detection sensor MAGNETIC POLE TESTER , ”LOUCAS” J that provides direct indication of magnetic pole. Manufactured entirely in Greece this device gives you the ability to find the poles on any magnet.Simply hold the pin at a distance of 1 cm. inclined and not vertically, press the button and activate the built-in electronic circuit that will indicate the magnetic pole through the LEDs.
For better detection of the pole boundaries of a magnet use the flux detector https://magnitech.gr/shop/hobby-diy/magnites-gia-xeirotexnia/flux-detector-150x150mm/

With the magnetic compass you can easily determine the poles of the magnets. The compass needle is always aimed at the north pole of a magnet. In this way, children in particular can easily understand and learn the basics of magnetism through play. In addition, the compass is the perfect companion for all outdoor activities. It is ideal for all camping enthusiasts or hikers. The compass helps you find your way in the right direction at all times. On a night hike, for example, you can’t get your bearings from the stars alone.
The magnetic compass is the best known type of compass. It acts as a marker in“magnetic north“, the local magnetic meridian, because the magnetised needle at its heart is aligned with the horizontal component of the Earth’s magnetic field. The magnetic field exerts a torque on the needle, pushing the north end or pole of the needle roughly towards the Earth’s north magnetic pole and pulling the other end towards the Earth’s south magnetic pole. The needle is mounted on a low-friction pivot point, and in better compasses it is mounted on a bearing so that it can be easily turned.
In navigation, directions on maps are usually expressed by reference to geographic or true north, the direction to the Geographic North Pole, the Earth’s axis of rotation. Depending on where the compass is located on the Earth’s surface, the angle between true north and magnetic north, also known as magnetic declination, can vary widely depending on geographic location. Most maps are given the local magnetic declination to allow the map to be oriented with a compass parallel to true north. The position of the Earth’s magnetic poles changes slowly over time, which is referred to as geomagnetic cosmic variation. This means that a map with the latest divergence information should be used.
Some magnetic compasses include means to manually compensate for magnetic divergence so that the compass shows true directions.
