Taylor was very excited today because her science teacher told the class that they would be making electromagnets in lab class. Taylor and her partner created an electromagnet by wrapping a copper wire around an iron nail. When they connected the wire ends to a battery, they were able to lift 3 paperclips with their electromagnet. The teacher wanted them to modify it so that it could lift more paperclips.

Explain how Taylor and her partner could modify the electromagnet so that it will lift 6 paperclips.

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.
