A compass needle is actually a weak magnet. Because in magnetism opposite polarities attract while like polarities repel, the needle's north pole seeks the earth's south pole and vice versa.

What tool helps you detect earth's magnetic field?
compass
A compass needle points northward due to earths?
magnetic field
Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?
This is FALSE. TWICE!The Earths magnetic Field is not Electromagnetic.A compass can be deflected by any Magnet.
What would indicate an magnetic field?
You can detect it by watching a compass needle, if that's what you mean.
A device that uses the Earths magnetic field to indicate witch way north is?
A compass.
How can you detect the presence of a magnetic field?
You can detect the presence of a magnetic field using a compass, which will align itself with the field lines. Other devices such as magnetometers can also detect and measure magnetic fields accurately. Additionally, certain materials, such as iron filings, can visualize magnetic field patterns when sprinkled around the area.
What magnetic fild do you detect when you go hiking?
You don't but your compass does: it's the Earth's own magnetic field's polarity and direction.
How does the magnetism in the compass work with the magnetism of earth so that the compass is a useful tool for navigating?
The magnetic needles of the compass align with earths magnetic field coming off the polar ice cap.
What of the following is evidence that an electrical current produces a magnetic?
You can detect the magnetic field by its pull on another magnet, including a compass needle.
How a compass can be used to trace the magnetic field of the magnet?
The pull of the magnet will over ride the earths magnetism. So the compass will react to the magnet as it passes through its field.
How a magnetic compass can be used to find directions on Earths surface?
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
