which is an important step in how an electric motor uses magnetic force to produce motion?\no as the north pole of the electromagnet nears the north pole of the permanent magnet, the current reverses and the poles of the magnets then attract.\no as the north pole of the electromagnet nears the south pole of the permanent magnet, the current reverses and the poles of the magnets then repel.\no as the north pole of the electromagnet nears the north pole of the permanent magnet, the current reverses and the poles of the magnets then repel.\no as the north pole of the electromagnet nears the south pole of the permanent magnet, the current reverses and the poles of the magnets then attract.
Answer
Brief Explanations:
In an electric - motor, when the north pole of the electromagnet approaches the north pole of the permanent magnet (like poles repel), the current reverses. This reversal changes the poles of the electromagnet so that the poles then attract, causing continuous rotation.
Answer:
As the north pole of the electromagnet nears the north pole of the permanent magnet, the current reverses and the poles of the magnets then attract.
