That depends. If we assume that current is flowing though the wire then there is an induced magnetic field equal to B=u_o*I/(2R*pi). For a visual refer to http://hyperphysics.phy-astr.gsu.edu/HBASE/magnetic/magcur.html#c2

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
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.
Why can't a compass might not point north if its placed near a wire with a current?
Current flowing through a wire induces a magnetic field, causing the compass to point away from "magnetic north" and point in a different direction.
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.
What happens when a compass is palced near a current carrying conductor?
If the conductor is carrying AC, no effect. If the conductor is carrying DC, then the compass needle will be deflected. Provided the two are close enough, and the DC current is strong enough.
What happens when a magnet is brought near a magnetic compass?
gago.
What happens when a bar magnet is brought near a compass?
gago.

When a compass pointing north will point in a different direction when placed near a piece of metal Which causes this to happen?
The needle in compasses is magnetic and is drawn to the Earth's magneticism in the North. When the needle is placed near a metal, as all magnets are, attracted to metals.
What happens in brachytherapy?
A source of radioactivity is surgically placed inside the body near the cancer

What happens when two like poles are placed near each other?
they create an electrical current
What happens when a compass is palced near a current carrying conductor?
If the conductor is carrying AC, no effect. If the conductor is carrying DC, then the compass needle will be deflected. Provided the two are close enough, and the DC current is strong enough.
When a compass is placed near a conductor where current flows its needle would deflect what does this indicate?
This proves that a magnetic field is developed around the conductor wen current flows through it...
What happens when a negatively charged object is placed near another negatively charged object?
They scoot away from each other
