Would the force deflect the wire if you reverse the current ina current carrying wire in a magnetic field?
yes,it would
Can 14-2 wire on a patio post be covered with white conduit?
Yes, that is fine as long as the wire does not run underground. If it does run underground you need 14-2U wire.
Do you need a mast to run aerial wire from a garage with a 100 amp fuse box to an office trailer?
Yes, it must have a standoff, and the proper service head in. I would run it underground instead of overhead. Use underground wire in a conduit.
What size service underground wire for 60amp at60 feet?
# 6 copper wire.
If a wire had a current which was continually reversing directions and hten was placed between the poles of a magnet what would happen to the force on the wire?
Draw an imaginary line between the poles of a horseshoe magnet, say horizontal. If the wire is along that line there will be no magnetic force on it because the current would be parallel /antiparallel to the magnetic field. If the wire is perpendicular to the line, say vertical, the magnetic force on the wire will be in then out. If the wire is perpendicular ,say in/out, then the magnetic force will be vertical up then down. That's what the magnetic force would be, It changes direction when the current changes direction. To actually see the effect however could be difficult because; the wire has to be part of a circuit which could cause problems giving it enough "freedom" to move. If you use household current, which changes direction every 1/120 th of a second, the wire will not have time to move very far before the force changes directions and its doubtful you will be able to see the motion. Finally even if the current changed more slowly you still need a pretty strong current (a few amps) and a pretty strong magnet to see the effect.
When a magnetic field is parallel to a current-carrying wire what is the force on the wire?
there is no force on the wire as the magnetic flux density on both sides of the conductor is the same. So, there is no net force on the wire
Are moving comfort sports bras any good?
If you are a C or D cup they are comfortable and supportive. Instead of the wire inside I like the compression sport bras that they have at Nike. They are supportive and very comfortable.
What is burial wire?
It is a wire with special insulation that protects it under ground. On the wire there will be a stamp "UF" or underground feeder. That means that it can be buried directly in the earth.
What gauge wire to use for 70 amp service going 200' underground?
I would recommend you use 1/0 gauge
What direction is a force exerted on the wire?
The answer depends on what is being done to the wire.
What is direct burial wire?
It is a wire with special insulation that protects it under ground. On the wire there will be a stamp "UF" or underground feeder. That means that it can be buried directly in the earth.
Telephone lines are allowed to sag when they are hung Why?
The less sag you want, the more force would be required to pull the wire.
