yes they do, anything that has energy in any form has an electromagnetic field surrounding it
no
A magnetic field has no discernable effect on your body. All of us are constantly exposed to a magnetic field, that of the earth itself, we cannot avoid it.
A magnetic field.
Hard magnets are those which require a high magnetic field so as to be magnetized. Soft magnets are those which acquire high magnetic flux when a little magnetic force is applied onto them.
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
Even a single atom can have a magnetic field. No larger components are necessary. However, we can also note that all magnets have a north pole and a south pole, so those can be considered to be components of magnets.
All magnets have a magnetic field. It is that property that defines them.
All magnets have a magnetic field If the object that you want to move by using the magnet is with in the magnets magnetic field it will move.
Magnets can retain a permanent magnetic field. All atoms have a magnetic field which are randomly arranged in the object. Magnets and ferrous metals can retain or temporarily align the atomic fields, thus they are magnetic.
A magnetic field.
I am not entirely sure what you are after, but you might say that:* It is the nature of magnets to be magnetic. Or:* It is the nature of magnets to be surrounded by a magnetic field.
they combine and become one magnetic field
The stronger the magnetic field is.
The 'magnetic field'
A magnetometer is a device used to measure the intensity and direction of a magnetic field.

The field gets stronger
