You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
Its invisible for a reason
It will slow down, the magnetic field will weaken, and it will become invisible.
This field is called magnetic flux. They are created by eddy currents from the coil itself and the energy running through it. This is where the energy of magnet is stored. You tap that energy to create power or hold objects that have a ferrous base.
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)
The magnetic field. If it's an electromagnet, the electromagnetic field.
The related link is a possible magnetic field. The dark portions are the strongest and the further you move away from the dark the field gets weaker. See related link.
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
a magnetic field
A magnetic field is the invisible field of magnetic force that is exerted on substances that are sensitive to magnetism. Magnetic fields have been studied by scientists and are used in applications such as compasses and MRI equipment.

Tantalum itself is not magnetic (does not generate the magnetic field); however, it is a paramagnetic material...meaning it will react to a magnetic field. see Paramagnetic

iron fillings
Magnetic fields are bascially lines of force caused by magnetic poles. It is invisible, but you can track how the field lines are formed doing a small experiment. Spread some iron fillings on a tray. Then bring a magnet up close to the iron fillings but not too close. You can observe that the iron fillings move into the field lines of the magnet that you brought up close. That's a miniature of a magnetic field. The earth's magnetic field is much bigger.
A Magnetic Force
No, the Earth's Magnetic Field acts just like a BAR Magnetic. It has a North and South Pole and its magnetic lines of its force field are more tightly 'compressed' near the Poles than at the Equator. See the image below for an example, or Google "magnetic field lines".
A bar magnet creates an invisible magnetic field around it, and magnetic metals such as iron are attracted to the magnet. Any metal structure is then included in the magnetic field lines. For iron filings on the sheet of paper, they will group into clusters near the poles, and also form an oval pattern along the length of the magnet, representing the magnetic field lines. The field is bulged outward nearest the center of the magnet's length. This displays the approximate two-dimensional shape of the three-dimensional magnetic field. For a picture, see the related link.
