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 direction does a wire point towards when a compass is placed nearby?

When a compass is placed near a wire, the wire points in the direction of the magnetic field created by the electric current flowing through the wire.


Why does a compass needle placed near a current carrying wire show deflection?

A compass needle placed near a current-carrying wire shows deflection because the moving charges in the wire create a magnetic field around the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align with the direction of the current flow in the wire.


What happens when a compass is palced near a current carrying conductor?

When a compass is placed near a current-carrying conductor, the magnetic field produced by the current can interact with the compass needle, causing it to deflect from its original position. This phenomenon is known as the magnetic field produced by the current affecting the magnetic needle in the compass. The direction of the deflection will depend on the orientation of the current and the compass in relation to each other.


What happens to a compass when it is brought near a current-carrying wire?

When a compass is brought near a current-carrying wire, the magnetic needle of the compass will align itself perpendicular to the wire due to the magnetic field created by the flowing current. This effect is known as the right-hand rule for electromagnetism.


Why does a compass change direction when it is near a current-carrying wire?

A compass needle is deflected when placed near a current-carrying wire due to the magnetic field generated by the flow of electric current. The magnetic field produced by the current interacts with the Earth's magnetic field, causing the needle to align in a different direction.

When a compass pointing north will point in a different direction when placed near a piece of metal Which causes this to happen?

The magnetic field generated by the piece of metal interferes with the Earth's magnetic field, causing the compass needle to deviate from pointing north. This happens because the compass needle aligns itself with the combined magnetic field in its vicinity.

Why does a compass needle move when placed near a wire carrying an electric current?

A compass needle moves near a wire carrying an electric current due to the magnetic field generated by the flow of electrons in the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align itself with the direction of the current flow.
