Answer;

Proportional to the charge of the magnet

Explanation;A magnet is a substance or a material that has the capability of producing magnetic field. Magnets may repel or attract poles of another magnet. based on the basic law of magnetism, like poles of magnets repel each other while unlike poles of magnets attracts each other.Therefore, magnets exerts forces on each other. These forces of attraction field of magnets are as a result of currents of electrically charge electrons orbiting in the nuclei of the particles that are in the material making up the magnet. The strength of these forces is proportional to the charge of the magnet.
Answer;

counterclockwise in the horizontal plane

Explanation;Using the right hand grip rule, the direction of magnetic field produced by a current carrying conductor or wire can be determined.Right hand grip states that if one grasps the wire or the conductor using the right hand, such that the thumb points the direction of the current, then the other four fingers shows or points the direction of the magnetic field produced.Therefore, if the direction of the current is upward then using the right hand grip rule the direction of magnetic field will be counter clockwise on a horizontal plane.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this. hope that you like the video and that it explains more in detail to you.

that is the link.
