Consider the following students' statements about the magnetic force on a positively charged particle placed at rest near a permanent magnet.

Bob: "A positively charged particle placed near the N pole of a permanent magnet will experience a MAGNETIC repulsion."
Nora: "A positively charged particle placed near the N pole of a permanent magnet will experience a MAGNETIC attraction."
Aaron: "A positively charged particle placed near either the N or S pole of a permanent magnet will not experience any magnetic force."

Which of these students is correct?

the body's situation won't change the forces are equal opposit and on the same body

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.
