∙ 12y agoWell a reguler magnetic field is fine because if you carry magnetic objects or metal it won't be harmed however you walk over an external magnetic field with metal or magnetic objects you will be stuck there forever because external means above ground

∙ 13y agoA magnetic field is the area surrounding a magnet in which the effects of that magnet may be observed.
A magnetic field is represented by imaginary lines of force which we call magnetic flux (symbol the Greek letter, 'phi'). Flux is measured in units called webers (pronounced 'vay-bers'). Its intensity is called magnetic flux density (B), defined as the flux per unit area, measured in webers per square metre, given the special name tesla.

What is the difference between a magnet and a rare earth magnet?
A magnet ie. the the ones on your fridge are made by manufactures pushing electrical current through ferrous metals causing them to have magnetic properties. Rare earth magnets are naturally occurring elements that have magnetic properties by themselves.
Why do the magnetic poles move around?
Because the metals in the hot center of our earth are moving arround.
The north pole of a compass magnet points toward?
The north pole of a compass magnet points more or less towards the north.Since opposite poles of a magnet attract, that means that the north pole of the magnet points towards Earth's magnetic south pole, which of course is located towards the north. Confusingly, this magnetic south pole has often been called the magnetic NORTH pole, precisely because it is located towards the north.
Is granite magnetic?
Granite can be slightly magnetic. If you bring rare earth magnet towards it, the magnet attracts. Especially if it is mined from India. Oxides of iron and titanium are responsible for this.
What is The part of a magnet that points north is called?
The pole of the magnet that points to earth's magnetic north is the south pole of the magnetIt should be understood that the north pointing end of a compass is a North magnetic pole. That being so, the north pole of the earth got its name because of this fact. Actually, the north pole of the earth has a South magnetic polarity which attracts the north pole of the compass. The south pole of a magnet points to the south pole of the earth because the south pole has a north magnetic polarity. Confused? Just remember that true (magnetic) north resides in the magnet; not in the earth. dbm 7/16/09Clearer AnswerThe above answer is incorrect. The poles of a magnet were named after the directions in which they point. The earth's poles were NOT named after a magnet's poles!When a horizontally-suspended comes to rest, it points in an approximately North-South direction. For this reason, the end of the magnet pointing North was called the 'North-Seeking' pole, and the other end was called its 'South-Seeking' pole. We no longer use the terms 'seeking', and we now call the ends of a magnet its 'north pole' and 'south pole' and these terms are also used to define their magnetic polarities.To differentiate it from True North and True South, we say that the magnet actually points to Magnetic North and Magnetic South -these are the names given to directions (or location) NOT their magnetic polarities. So, because 'unlike poles attract', the magnetic polarity at the location we call 'Magnetic North' is a south pole which therefore attracts the north pole of a magnet.

Why does earth attract a magnet if magnetic force is greater than the gravitation force?
Earth attracts a magnet because both Earth and the magnet have mass. The force of gravity acts between any objects that have mass.
What are the differences between natural magnets and artificial magnets?
magnet which we get naturally from earth is called natural magnet e.g: lodestone.. while magnet made from magnetic material is called artificial magnet ...
Earth has a strong magnetic field and is essentially a big magnet Where are the magnetic fields strongest on Earth?
Algeria haha
Can any magnet detect earth magnetic field?
Yes
What object that attracts iron?
none of them. iron can be magnetised but the material itself is not magnetic
How a compass works and why it is useful?
A compass has a magnet that points north, according to the Earth's magnetic field. It is useful, precisely, to find out where north is.A compass has a magnet that points north, according to the Earth's magnetic field.

Is the magnetic pole another name for the south pole?
No. The Earth is a spinning sphere, and the axis of the rotation matches the Earth's surface at the north pole and the south pole. If the Earth had an axle, that's where they would poke out. The Earth is also a giant magnet, like an enormous bar magnet. The orientation of this magnet, and the magnetic lines of force from it, are not lined up with the physical axis of the Earth's rotation. The "north magnetic pole" is somewhere in northern Canada, while the south magnetic pole is in Antarctica. When navigating with a magnetic compass, the compass doesn't point at the north pole; it points to the north MAGNETIC pole. In most of Europe, there wasn't a whole lot of difference, but in North America, the difference between true and magnetic north can be dozens of degrees. Navigational maps will list lines of "magnetic variation", which is the difference between true north and magnetic north, so that you can apply the appropriate correction.
What is the angular difference between true North and magnetic North is called?
That's the "magnetic declination". Since the true north pole and the magnetic north pole are located at different points on the earth, the declination is a different angle in different places on earth.
What is the difference between the magnetic poles and the geomagnetic poles?
The Geomagnetic poles (dipole poles) are the intersections of the Earth's surface and the axis of a bar magnet hypothetically placed at the center the Earth by which we approximate the geomagnetic field. There is such a pole in each hemisphere, and the poles are called as "the geomagnetic north pole" and "the geomagnetic south pole", respectively. On the other hand, the magnetic poles are the points at which magnetic needles become vertical. There also are "the magnetic north pole" and "the magnetic south pole". The geomagnetic or magnetic south (north) poles correspond to the N (S) -pole of a magnet.
Why do the magnetic poles move around?
Because the metals in the hot center of our earth are moving arround.
