Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
What direction does a compass needle point if a current carrying wire is wrapped around it?
The compass needle aligns itself parallel to the direction of the lines of magnetic force where it happens to be. It does not 'point to a particular pole' for that is beyond the sensibility of a simple bar of metal. I repeat, it aligns itself parallel to the lines of magnetic force ...
Does a compass needle exert force on the earth if the earth exerts a magnetic force on the compass?
Yes !! But its negligible.
What does force on a magnetic compass needle represent?
magnetism
If Veronica spins in a circle with the compass in her hand which force keeps the compass' needle pointing north?
Magnetic Force

Do compass needles pointing to direction considered as contact force?
No, magnetism (the force that makes the needle turn) is a non-contact force.
Why does the compass point north in the southern hemisphere?
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.

What direction does the needle on a compass point when a horseshoe magnet is put beside it?
The direction of the needle will remain unchanged. This is due to magnetic forces, the needle will remain in line with the lines of magnetic force which flow between the north and south poles.
What does force on a magnetic compass needle represent?
magnetism
If Veronica spins in a circle with the compass in her hand which force keeps the compass' needle pointing north?
Magnetic Force
How does a compass needle align itself?
A compass needle aligns itself with the Earth's magnetic field because it is a magnet itself. The north-seeking end of the needle is attracted to the Earth's magnetic north pole, causing it to point in a north-south direction.
A compass needle changes direction if the flow of electricity in the wire near it is reversed.?
The only way to make current flow through a compass needle is to connect a wire to each end of the needle. When you do that, the direction the needle points is completely determined by the wires, and it's no longer free to rotate. So I'd say that nothing at all interesting happens.
A fixed pulley changes the blank of a force?
changes the direction of a force
What is a plotting compass?
A plotting compass is a small magnet which is suspended and is free to rotate. When it is near a magnet, the compass will always point in a particular direction (the north pole's direction) becasue of the force of the magnetic field.
