A cylindrical capacitor is being charged by an exponentially decreasing current. The inner cylinder of the capacitor is positive and the outer cylinder is negative. What is the direction of the magnetic field between the two cylinders while the capacitor is charging

Ireally don’t know

Answer(b) 60 miles per hour;

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.
