A car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion and the correct option is option A.
What are electromagnets?Electromagnets are made out of a coil of wire (wire curled in series).
This is more effective in producing a magnetic field than just a wire running straight.
This effect can be strengthened by winding a wire tightly around a powerful core made of magnetic material, such as iron.
The strength of the magnetic field is proportional to the number of turns made around the iron core and how tightly they are wrapped around.
Therefore, a car manufacturer can add coils to the electromagnet and increase the size of the magnets causing the rotational motion and the correct option is option A.

What is an ellipse please help)
In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.
Maybe they might use that math thing for Science.

Question:
A 250mL Erlenmeyer flask weighing 55g contains 5g of sodium bicarbonate. To this, an excess, 15g, of acetic acid is added to the flask. While swirling, many bubbles are present. Finally, you stop swirling the flask, and the bubbles stop. You then place this flask on an analytical balance. The mass registers 73g.
How does this final mass compare with the value expected according to the Law of Conservation of mass?
Why do you believe that this comparison exists?
State the Law of Conservation of Mass. Do these results break this law? Why?
What changes, if any, could be made to the procedures in this experiment to allow a closer comparison to what the Law of Conservation would expect?
