Who invented the electric motor?

The electric motor is a device that converts electrical energy into mechanical energy using the principle of electromagnetism. The first electric motor was invented by Michael Faraday in 1821. Faraday’s work demonstrated that electric current flowing through a wire could create motion in a magnetic field, laying the foundation for modern electric motors.

Faraday’s experiments showed that a wire carrying an electric current could rotate around a magnet due to the force exerted by the magnetic field. This simple setup was the earliest example of an electric motor, although it was not practical for large-scale use at the time. His discovery proved the relationship between electricity and magnetism, which is a cornerstone of electromagnetism in physics.

Other inventors mentioned in the options contributed to different areas of science and technology:

• 
  

  Oliver Evans designed early steam engines but did not work on electric motors.

  
  


• 
  

  Thomas Edison invented practical electric devices like the light bulb, but not the motor itself.

  
  


• 
  

  Horace Day is not related to the invention of the electric motor.

  
  

Modern electric motors are more advanced and use Faraday’s principles to power machines, fans, vehicles, and appliances worldwide. Understanding Faraday’s contribution is important in physics and engineering, as it explains how electricity can produce mechanical motion, which is essential for numerous technological applications.

In summary, the electric motor was invented by Michael Faraday, and his experiments established the key principles of electromagnetism that drive the working of all electric motors today.
