The voltage generated by a battery or a magnetic field is called

• A. Electromotive Force
• B. Induced Voltage
• C. Terminal Voltage
• D. Potential Difference

Answer: (A)

Electromotive force is the energy per unit charge that a source, such as a battery or generator, can supply to move charges around a circuit. It represents the pushing power the source provides to drive current, whether the energy comes from chemical reactions inside a battery or from electromagnetic processes in a generator. Induced voltage is related but describes a voltage produced specifically by changing magnetic flux, not the general energy-providing ability of a source. Terminal voltage is the actual voltage across the device’s terminals under load, which may be lower than the emf due to internal resistance. Potential difference is a broad term for voltage between two points but doesn’t specify the energy source driving the current. So the voltage generated by a battery or a magnetic field is electromotive force.
