A magnetic field of magnitude 0.470 T is directed parallel to the plane of a circular loop of radius 87.0 cm. A current of 7.40 mA is maintained in the loop. What is the magnetic moment of the loop? (Enter the magnitude.)

Ibelieve your answer is b.hope this : )

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.
