Question

Which changes in an electric motor will make the motor stronger? Check all that apply. using a stronger permanent magnet using a weaker permanent magnet increasing current in the electromagnet decreasing current in the electromagnet increasing the distance between the magnets decreasing the distance between the magnets

Answer 1

use stronger magnets
increase current
push magnets closer to coil
adding more sets of coils

Answer 2

The following changes will make the motor more stronger

• Using strong permanent magnets
• Increasing the current
• Decreasing the space between magnets

Step-by-step explanation:

Using string magnets will produce strong flux and the motor will become strong. The internal flux also deepness upon the strength of coil. Similarly by increasing current we can make the motor more powerful because according to power equation P=VI so increasing the current will increase the product of voltage and current resulting more power. In the same way by reducing the distance between magnets will make the motor stronger because the flux and torque will increase.
