An electric motor uses regular magnets and an electromagnet to create motion. The attracting and repelling forces create rotational motion along with the electric current from the electromagnet. What can a car manufacturer do to make an electric motor stronger?

Question

A. car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion.
B. car manufacturer adds coils to the electromagnet and decreases the size of the magnets causing the rotational motion.
C. car manufacturer can remove coils from the electromagnet and increase the size of the magnets causing the rotational D. car manufacturer can remove coils from the electromagnet and decrease the size of the magnets causing the rotational motion.

Answer 1

To make an electric motor stronger, a car manufacturer can enhance the strength of the electromagnet and the overall magnetic field that contributes to the motor's performance. Based on the options provided, the most effective choice would be:

A. Car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion.

Adding more coils to the electromagnet will increase the magnetic field strength generated when current flows through the coils, and increasing the size of the permanent magnets will also boost the magnetic field strength. Together, these modifications will enhance the overall torque and efficiency of the electric motor, leading to stronger performance.
