Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
An electric current produces a magnetic field around wires where the current exists.

One simple way to measure magnetic fields is by using a device called a magnetometer. Magnetometers can detect and measure the strength of magnetic fields in a given area.
A magnetic needle meter, or a simple compass.
Because the entire concept of magnetic field is based on the element IRON (and to a much lesser degree, Nickel). Iron content? (most metals): Magnetic. Plastic based? (no iron): Not magnetic. Simple as that.
Are you referring to the definition to be simple or the definition of "simple predicate"? Anyway, I'm thinking that you mean the former. A simple predicate is the word that shows what is happening. In the before sentence, is is the simple predicate. "is the word that shows what is happening" is the whole predicate. A verb will not always be the simple predicate, and simple predicates will not always be 1 word.

The definition of chemistry easy is the study of elements, laws of combination and behavior. The definition of simple is having only one thing or element to do.
Ink is not typically magnetic, so a simple way to determine if ink is magnetic is by using a magnet. If the ink is attracted to the magnet, then it contains magnetic particles.
