A compass detects the Earth's magnetic field, allowing it to determine the direction of magnetic north. This is achieved through a magnetized needle that aligns itself with the magnetic field lines. Compasses are commonly used for navigation and orientation in various environments, helping users find their way by indicating cardinal directions.

You can detect it by watching a compass needle, if that's what you mean.
A magnetic needle meter, or a simple compass.
By using a compass, iron filings, and iron objects, you can detect the presence and direction of a magnetic field. The compass will align itself with the magnetic field lines, indicating the magnetic north. Iron filings will visually demonstrate the shape and strength of the magnetic field, as they will align along the field lines. Additionally, the influence of nearby iron objects can distort the magnetic field, showing how they interact with the compass and filings.
You can use a compass to detect the Earth's magnetic field and determine cardinal directions like North, South, East, and West. By aligning the compass needle with the magnetic field, you can navigate and orient yourself accordingly.
You don't but your compass does: it's the Earth's own magnetic field's polarity and direction.
A plotting compass is used to detect which direction the North Pole is located. You can stand in any position and it will always point north. +++ That's a navigation compass. A plotting compass will indeed point to the Earth's Magnetic North Pole (not the axis pole), if not influenced by any other magnet; but its purpose is in plotting the magnetic field around a magnet.
Ferrous ore contains iron, which is magnetic. When you hold a compass near ferrous ore, the iron in the ore can affect the magnetic needle of the compass, causing it to deviate from its usual direction. By observing any unusual behavior in the compass needle, you can potentially detect the presence of ferrous ore nearby.
A compass can detect an electric current because a moving electric charge produces a magnetic field around it. When an electric current flows through a wire, it creates a magnetic field that can be detected by the compass needle. This phenomenon is known as electromagnetism.
You can detect the magnetic field by its pull on another magnet, including a compass needle.
A magnetometer is a device used to detect changes in the strength and orientation of magnetic fields. It is often found in devices like smartphones to provide functions such as compass directions and motion sensing.
