Question

question 27
which of these statements describes how an electric motor works?
electricity creates a magnet that causes other parts of the motor to move
a permanent magnet is turned into an electromagnet using electricity
electricity is used to move a turbine
moving turbines cause magnets to move, producing electricity

Explanation:

An electric motor operates based on the principle that electricity creates a magnet (electromagnet). This electromagnet interacts with other parts (like permanent magnets in some cases) to cause motion. A permanent magnet can't be turned into an electromagnet (an electromagnet is a coil - wire with current, not a modified permanent magnet). Electricity moving a turbine is more related to power generation in some power plants (like in a steam - powered electricity generation where steam moves the turbine, and in some cases, electricity can be used to move a turbine in a motor - like application but it's not the fundamental description). Moving turbines causing magnets to move for electricity production is the principle of a generator (reverse of motor in some sense).

Answer:

Electricity creates a magnet that causes other parts of the motor to move
