Ques:Q: Motors are the most common application of magnetic force on current-carrying wires. motors have loops of wire in this? Read this paragraph and choose the correct option from the provided answers: 22.8 Torque on a Current Loop: Motors and Meters Motors are the most common application of magnetic force on current-carrying wires. Motors have loops of wire in a magnetic field. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. Electrical energy is converted to mechanical work in the process. (See Figure 22.34. Choices: - electrical circuit - capacitors - spark plugs - magnetic field A:

Ans:magnetic field
