Question

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)

Answer 1

When a magnet with the N pole is moved towards the loops (coils) connected to a light bulb, the light bulb will light up.

Step-by-step explanation:

When a magnet with the N pole is moved towards the loops (coils) connected to a light bulb, the result is that the light bulb will light up. This is because when a magnetic field is changing in strength or direction near a conductor, it induces an electric current in the conductor. In this case, the movement of the magnet towards the loops causes a change in the magnetic field, which in turn induces a current in the loops and lights up the bulb.

Answer 2

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.
