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.
Because the primary purpose of a compass is to react to the magnetic field of the earth, it get affect by a nearby compass when the compass' magnetic field is stronger than that of the earth. As the magnet is moved away, the strength of its field diminishes and the compass goes back to 'normal' - pointing north.
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
When a small compass is placed in a magnetic field, the needle of the compass will align itself with the direction of the magnetic field. This is because the needle is magnetized and responds to the magnetic forces in the surrounding area.
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.
A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the compass will deflect, and realign itself along the north/south axis of the SUM of the fields.
If a compass is placed on a metal trunk, the magnetic field around the trunk may interfere with the compass needle, causing it to point in the direction of the metal trunk rather than true north. This can result in inaccurate readings and make it difficult to determine the correct direction.

The furnace filter should be placed with the airflow direction arrow pointing towards the furnace.
The filter should be placed in the furnace with the airflow direction indicated on the filter facing towards the blower motor.

No. The true north pole and the magnetic north pole are in different locations. The compass will point at the magnetic north pole. If you happened to be somewhere between the two north poles, the compass will point exactly backwards!
The filter in the furnace should be placed with the airflow arrow pointing towards the direction of the airflow, typically facing towards the blower motor.
