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.

Is a compass affected by the earths magnetic field?

Yes, a compass works by aligning itself with the Earth's magnetic field to determine direction. The needle in a compass is magnetized and will point towards the Earth's magnetic north pole.


How do i use the earth's magnetic field to tell me where to go?

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.


How a compass can be used to trace the magnetic field of the magnet?

A compass can be used to trace the magnetic field of a magnet by placing the compass near the magnet. The needle of the compass will align with the magnetic field lines, allowing you to visualize the direction of the field. By moving the compass around the magnet, you can map out the shape and direction of the magnetic field.


What would indicate an magnetic field?

You can detect it by watching a compass needle, if that's what you mean.


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.


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.


Compass magnets can only be deflected by electromagnets such as Earth's magnetic field?

Compass magnets align themselves with Earth's magnetic field due to their own magnetic properties. Electromagnets, like the one found in devices such as phones or microwaves, can create magnetic fields that may interfere with a compass's accuracy if they are strong enough and placed close to the compass.


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.


What do you have to add to a compass to make it in line with the earths magnetic field?

Nothing. That's exactly what a compass does ... as long as it's free to turn, and there are no ferrous metals or other sources of magnetic fields nearby.


What happens when a compass is brought into a magnetic field?

When a compass is brought into a magnetic field, the needle of the compass will align itself with the magnetic field lines. This is because the needle is a magnet itself and is influenced by the magnetic field of the Earth or any external magnetic field it is brought into.
