Since the needle in a compass is magnetized by induction it loses its magnetism easily by rough contact or heat.
It cost is very expensive
The prismatic compass is a type of compass use for survering a land.
maybe you will get electrocuted?
If the power lines were Direct Current, sometimes used for efficient long distance transmission, then your compass would definitely be affected, and may be quite useless. The high currents in such a long distance DC line will generate a magnetic field. With an Alternating Current power line, the alternating current itself should not cause any problem with the compass, but the steel of the towers themselves may certainly do so.
All forms should be well constructed.All forms should be carefully aligned.It should be subtle and firm.All forms should be securely braced and fastened together in their final position.
Carefully and Correctly
Depends from which height. If it's a short distance chances are it will remain as it was before. If it's from a long distance it will probably be damaged to a certain extent. Basically the same answer if you dropped anything although a compass is certainly more fragile.
carefully
Carefully
There should be two bolts on each side of each handle. Get a screw and as carefully as you can unscrew them and tack the handle off.
very carefully
Very, very carefully.
Carefully and correctly, otherwise their injuries may become more serious or possibly fatal.
You should never see a fence on a compass.
It cost is very expensive
Yes, but only if they handle them carefully. The tarantula is docile and its bite isn't as deadly as often believed, but it is painful.
Extremely carefully. Muriatic (hydrochloric) acid is not something you should be messing around with if you don't know how to handle it safely.
