If you are magnetising a needle what direction you must always stroke?

The idea is to line up the electrical fields of the atoms, and to do that you have to stroke in one direction or the other. However, whether you stroke left to right or right to left doesn't matter.


How can a simple compass be made using a magnet?

Repetitively stroke a pin which CID attracted to the magnet in 1 direction for two minutes (stroke, lift, back, down, stroke, etc.). Stick the needle in a cork and put it in some water - one end will point north and the other south.


How can you magnetise a needle?

There are several ways. 1. Stroke the needle in one direction, with another magnet. 2. Place it in a coil of wire and pass a large (DC) current through the coil for a few seconds. (This is how they would do it commercially) 3. Align the needle with the magnetic north/south direction, now hit it several times. It will eventually take on the earths magnetic field as it's own.

What to do if your lawnmower 2-stroke engine has a varying RPM problem?

RPM variation in a 2-stroke can be caused by several reasons, but the most common is fuel supply. Check the external fuel filter, if it has one, if not, check the fuel pick-up filter inside the fuel tank. If the filter is not the problem next check the float and the needle valve and seat. If the float-needle is not moving freely it will need replaced. The variation in RPM is usually caused by fuel starvation then brief recovery in repeated cycles.
