To keep the bar moving at a constant speed, the external force must exactly oppose the magnetic force's x-component.

How does the magnetic force function?

While opposite poles are drawn to one another, the same poles repel one another. When you rub an iron object against a magnet, the north-seeking poles.

What is the force's direction when it is applied to a moving object?

Moving things are subject to the force of friction, which acts in the opposite direction to the motion.

What does physics' right-hand rule entail?

Using the right-hand rule, we may recall this diagram. If you move your pointer finger in the same motion as the positive charge.
