It is a magnet or a electro-magnet. If you are trying to use it as a metal detector then you will need a really strong magnet!
Any object that is nuetral that does not have magnetic pole's
[object Object]
Each atom acts like a tiny magnet. When the atoms are aligned, the magnets produce magnetism. When an iron or nickel material comes near the magnet, its atoms align with the different pole facing the magnet. For example, if the magnet's atoms have the North side facing away, then the iron object will have the South side facing the magnet. So then they attract.
Magnetism is the number of magnetic moments per unit of volume. It is the volume of the magnet which determines the magnetism. If an object has great weight and great volume, it will be a strong magnet. If an object has great weight but lesser volume, the magnetism will be weaker.

No, a magnet is a physical object. However, a magnet can EXERT a force.
the spectrum change with direction, either from you or away
The Doppler effect
smaller
the weight of an object grows more
Yes, the closer you get the bigger the object will appear but to only the size of the object really is, and the farther away you get the small it will get
When an object moves away from us, or towards us.
an magnet is a object that attracts or repel
the metal object becomes a temporary magnet
These wee steel bars are known as riders, and they mark the travel extent of the Mercury column. They are held in place by a feeble magnet. When the reset button is pushed, it moves the magnet away from the tube, and the riders will settle.
