HEL A wire of length 0.15 m carries a current of 1.0 A in a magnetic field with
magnetic flux density of 2.0 mT.
Find the force on the wire if it is:
a) perpendicular to the magnetic field lines

b) parallel to the magnetic field lines.

The next element is345640

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.
