which changes in an electric motor will make the motor stronger? select 3 options. 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

Answer:

  • using a stronger permanent magnet
  • increasing current in the electromagnet
  • decreasing the distance between the magnets

Explanation:

Step1: Magnetic - field strength impact

A stronger permanent magnet creates a stronger magnetic - field, which increases the force on the electromagnet, making the motor stronger.

Step2: Current - related force

According to Ampere's law, increasing the current in the electromagnet increases the magnetic force it generates, enhancing the motor's strength.

Step3: Distance - force relationship

The magnetic force between two magnets is inversely proportional to the square of the distance between them. Decreasing the distance between the magnets increases the magnetic force, strengthening the motor.
