A blender that uses electric current to turn its blades is an example of an electric motor.

Here's why:

* Electric motors convert electrical energy into mechanical energy. In the case of a blender, the electric current powers a motor that spins the blades.

* Electric current creates a magnetic field, which interacts with another magnetic field (often within the motor itself) to produce rotation.

* This rotational force is what makes the blades of the blender spin.
