The magnetic field can certainly be detected by a compass.
The 'lines' are a handy human invention, and don't really exist, so you could not,
say, trace out the lines with a compass, because they're not there.
But place a compass next to a wire that's involved in any battery-operated (DC)
circuit, and the compass absolutely goes crazy !
Yes. Of course, you have to have a suitably sensitive suspension.
You can certainly use one to measure some properties and aspects of earths magnetic field.
Yes definitely. Using a compass needle we can map the magnetic field around a bar magnet.
Yes, if you specifically mean a magnetic compass. That's what a magnetic compass does: align itself to magnetic fields.
A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

no they are not
Your compass needle will align itself with the lines of magnetic force at your location. This will diverge from the simple 'earth monopole model' depending on the local magnetic field, and any local geomagnetic anomalies.On most topographic maps, the 'magnetic deviation' and its annual variance will be marked on the map legend. Where i am it is about 25 degrees east of the true magnetic north.
The copper by itself will do nothing of the sort. It will be surrounded by magnetic field lines if a current flows through it. It is the current that produces the magnetic field lines.
That is because the map is used with a magnetic compass. Since the needle on the compass points in the direction of magnetic north it is easier to use the map with the compass if the lines drawn on the map indicate magnetic north.
A compass needle will align itself with a magnetic field. It will want to lie along the magnetic field lines, or lie parallel to the lines of force of the magnetic field it is interacting with.
Using a compass is the easiest way. The needle is going to point to the Magnetic North Pole. That means that the compass needle is ALIGNED with the Magnetic Field Lines of the Earth's magnetic field at your current position.
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
A magnetic compass acts in relation to the Earth by aligning a magnetised needle with the lines of the Earth's magnetic field; thus resulting in a needle which points to magnetic North.
if a bar magnet swings freely it will act like a compass.
A compass has a needle that is magnetized. This needle is suspended so that it can rotate freely and it can align itself with any magnetic field it is exposed to.If you put a magnet close to a compass, the needle will align itself with the magnets magnetic field.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.
From that list, I'll have to go with 'B'.
Get a magnet that's free to turn in any direction ... a boy-scout compass will do nicely.Place it in the magnetic field. It rotates to point in the direction of the field 'lines' atthat location. (I forget whether it's the north or south pole of the compass that pointsin the direction of the magnetic field, or opposite to it.)If you like, move your detector slowly, always following the direction in which it points,and you'll trace out a complete 'line' of the magnetic field.
They are called the magnetic field lines.
Magnetic field lines don't cross.
A plotting compass is a small magnet which is suspended and is free to rotate. When it is near a magnet, the compass will always point in a particular direction (the north pole's direction) becasue of the force of the magnetic field.
