An electromagnetic field is a physical field produced by electrically charged objects. The field can be viewed as the combination of an electric field and a magnetic field. The electromagnetic field may be viewed in two distinct ways: a continuous structure or a discrete structure.
Cells that detect and respond to electromagnetic fields, allowing for the detection of magnetic fields.
Electromagnetic fields can be varying in intensity. A magnet is static.
Water is matter. Electromagnetic energy is energy in the form of electric fields and magnetic fields.

by electromagnetic fields
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other and are in phase.
No.
by electromagnetic fields
Yes
No. Electromagnetic fields have polarity.
It is not very clear what the question means. Light is an electromagnetic field and it can propagate in a vacuum. Propagation of a beam of light is unaffected by any other electromagnetic fields in its path.
No. An electromagnetic wave IS electric and magnetic fields.
