18.there is no battery in this simulation. move the magnet with the n pole toward the loops (coils) connected to the light bulb until the n pole barely passes the loops. what happens to the light bulb? (2 points)

Step-by-step explanation:

Whenever a magnetic field linked to loop changes, the current is induced in the loop which sequentially opposes the cause of change in magnetic flux. So whenever the magnet moves towards and away from the loop then it causes the current to induce in the loop to oppose the change in magnetic flux by effectively creating a similar pole that is coming towards the loop.

For example, if the magnet north pole is coming towards loops then it effectively creates a north pole in front of the magnet.

So flow of current will glow the light bulb.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
