Which changes in an electric motor will make the motor stronger? Select 3 options.using a stronger permanent magnetusing a weaker permanent magnetincreasing current in the electromagnetdecreasing current in the electromagnetincreasing the distance between the magnetsdecreasing the distance between the magnets

A stronger permanent magnet creates a stronger magnetic field. Increasing the current in the electromagnet also strengthens its magnetic field, and decreasing the distance between the magnets increases the magnetic force between them. Therefore, using a stronger permanent magnet, increasing current, and decreasing the distance make the motor stronger.
