Ike is conducting a scientific experiment involving clear adhesive tape. He completes each of the following steps below. Ike's teacher tells him that this process has caused each strip of tape to gain a negative electric charge. What could Ike do next to demonstrate that the negative charge of each strip has generated an electric field?

• see if the strips repel each other when brought close together

• see if the strips will stick together when the sticky sides are pressed together

• see if one of the strips is longer or more massive than the other

• see if the strips respond to the force of gravity when dropped from a height

Jacques moves a bar magnet near a circle of copper wire. Moving the magnet creates a changing magnetic field passing through the copper loop. What happens to the copper wire because of the moving magnet?

• The copper wire loses its magnetic charge.

• The copper wire develops a positive electric charge.

• The copper wire develops a negative electric charge.

• The copper wire carries an electric current.

Carl and Abby are discussing what they have learned in class about electricity and magnetism. Carl tells Abby that an electric current running along a wire can be used to produce a magnetic force. Abby, on the other hand, tells Carl that moving electrons through a magnetic field can produce an electric current. Which of the students is/are correct?

• Neither student is correct.

• Only Carl is correct.

• Both Carl and Abby are correct.

• Only Abby is correct.

Katie rubs a balloon against her hair. Electrons from her hair travel to the balloon, giving the balloon a negative charge and her hair a positive charge. When the negatively charged balloon is brought near the strands of Katie's hair, they move to get closer to the balloon, without the balloon actually touching them. This shows that

• Katie's hair would move in this way with or without the balloon.

• particles in the air must be pulling Katie's hair toward the balloon.

• electric attraction is a force that can act at a distance.

• electric attraction is a force that can only act on contact.
