Aconductor is formed into a loop that encloses an area of 1m^2. the loop is oriented at a angle 30 degree with the xy plane. a varying magnetic field is oriented parallel to the z axis. if the maximum emf induced in the loop is 10v, what is the maximum rate at which the magnetic field strength is changing?

Explanation:

As we know that flux of magnetic field from the closed loop is given by

now we will have

now we have

EMF = 10 Volts

probably not if net force is zero

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.
