What would happen if you placed a compass near an electromagnet?
You would not get a true reading any longer. The forces of the electromagnet are greater than the natural magnetism of the Earth.
Why does a needle of a compass move when you put a bar of metal close to it?
The compass needle is a magnet and as you have probably tried, a magnet will 'stick' to an Iron bar. Thus as you move the compass near the Iron, its magnetic field lines are bent by the Iron and become locally stronger than the field lines of the planet, deflecting the needle away from north.
Why does a compass needle move when placed near a wire carrying an electric current?
True... The wire carring current creates a slight magnetic field.
What happens to a compass when it is brought near a current-carrying wire?
the compass aligns with the magnetic field created by the wire
What did Humphrey Davy notice about a wire with electricity running through it as he brought it near a compass?
The compass needle was deflected.

When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.
What is local attraction on compass survey?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
How do you eliminate local attraction?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.

Why compass point towards north?
The compass has a small magnet, that can move around freely. This is affected by the Earth's magnetic field. The Earth's magnetic south pole is near its geographic northpole, but not exactly so.
Should you see a fence on the compass when your near the cattle ranch?
You should never see a fence on a compass.

Where on the compass is Spain located?
Spain is in southwestern Europe, near Portugal and France.
What did Humphrey Davy notice about a wire with electricity running through it as he brought it near a compass?
The compass needle was deflected.
What do you mean by magnetic affect of electric?
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
