What are the three properties of a magnet?

1. Magnets attract iron and other ferromagnetic materials such as neodymium and cobalt.

2. Magnets attract or repel other magnets.

3. In addition one part of a magnet will always point north when allowed to swing freely.

The properties of a magnet is 

all magnets have magnetic fields around them 

the field emerges from one pole of the magnet conventionally known as the North Pole or returns to the other such South Pole

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
