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?
a
A car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion.
b
A car manufacturer can add coils to the electromagnet and decrease the size of the magnets causing the rotational motion.
c
A car manufacturer can remove coils from the electromagnet and decrease the size of the magnets causing the rotational motion.
d
A car manufacturer can remove coils from the electromagnet and increase the size of the magnets causing the rotational motion.
