Answer 1

Правильный ответ 2 
направление  вертикально вверх должно быть

Answer 2

Direction of the Lorentz Force on a Negative Ion

When a negative ion enters the space between the poles of an electromagnet, it experiences a horizontally directed magnetic field. The direction of the Lorentz force acting on the negative ion can be determined using the right-hand rule.

The right-hand rule states that if you point your thumb in the direction of the velocity of the charged particle, and your fingers in the direction of the magnetic field, then your palm will face the direction of the Lorentz force acting on the particle.

In this case, the negative ion is moving horizontally between the poles of the electromagnet, and the magnetic field lines are horizontally directed. Therefore, the Lorentz force acting on the negative ion will be directed either vertically up or vertically down, depending on the direction of the velocity of the negative ion.

To determine the exact direction of the Lorentz force, we would need to know the direction of the velocity of the negative ion. Without this information, we cannot definitively say whether the Lorentz force is directed vertically up or vertically down.

So, the possible answers to the question "Where is the Lorentz force directed?" are:

1. Vertically down 2. Vertically up

Please note that the direction of the Lorentz force depends on the direction of the velocity of the negative ion, which is not specified in the question.
