Students attached both ends of a long wire to the poles of a battery and wrapped the wire around a spoon. In this arrangement, the spoon is able to pick up five paper clips. The students wrap more wire around the spoon and want to determine if the strength of the magnetic force has increased. Which of the following observations would indicate that wrapping more wire has increased the strength of the electromagnet?

More wire was needed to wrap around the spoon.

The spoon now picks up seven paper clips.

Eventually, the battery runs out of energy.

The ends of the wire must touch the battery's poles.

The table provided shows data collected by students during an investigation of two electromagnets. Which of the following conclusions is supported by data on the table?

When two electromagnets are of like charges, they attract each other.

Electromagnets that repel each other have more force than those that attract each other.

The greater the charges of two electromagnets, the greater the size of the force.

If the charge on one magnet is positive, the charge on the other must be negative.

This table shows the magnitude of electromagnetic force exerted by two electromagnets on each other as the distance between the two electromagnets is varied. The data on the table provide evidence for which of the following conclusions?

The force between any two magnets is always constant, regardless of distance.

As distance between electromagnets increases, the electromagnetic force also increases.

The smaller the distance between two electromagnets, the greater the force.

The force between two magnets depends only on the charge of the electromagnets.
