Metal paper clips do not attract or repel each other. When an electromagnet is placed nearby, the paper clips can be observed to move toward it. Which statement describes this phenomenon?(1 point) Responses Magnetic domains within the paper clips align with the magnetic field. Magnetic domains within the paper clips align with the magnetic field. Paper clips turn into permanent magnets after exposure to a magnetic field. Paper clips turn into permanent magnets after exposure to a magnetic field. The electromagnet reacts to the strong force of attraction from paper clips. The electromagnet reacts to the strong force of attraction from paper clips. Electrons flow freely into the magnetic field, causing the paper clips to move.
The correct statement describing this phenomenon is: Magnetic domains within the paper clips align with the magnetic field.
Use the model of a magnetic field generated by an electromagnet to answer the question. Which statement about the current and magnetic field correctly describes this figure as well as all electromagnets? (1 point) Responses The current, which points upward, is generated by the sporadic magnetic field. The current, which points upward, is generated by the sporadic magnetic field. The current generates and is perpendicular to the magnetic field. The current generates and is perpendicular to the magnetic field. The current generates the magnetic field and is parallel and opposite to the direction of the magnetic field. The current generates the magnetic field and is parallel and opposite to the direction of the magnetic field. The current generated by the magnetic field is parallel and points in the same direction as the magnetic field
The correct statement about the current and magnetic field is: The current generates the magnetic field and is parallel and opposite to the direction of the magnetic field.
Domains are the regions in a material in which the magnetic fields of many of the atoms are aligned facing the same direction. What is the relationship between the electrical current and the alignment of atoms responding to the current?(1 point) Responses As current decreases, the alignment becomes continuous. As current decreases, the alignment becomes continuous. The alignment of atoms has nothing to do with the changing current. The alignment of atoms has nothing to do with the changing current. As current increases, the alignment reverts to its random arrangement. As current increases, the alignment reverts to its random arrangement. As current increases, the alignment becomes more organized.
The correct statement is: As current increases, the alignment becomes more organized.
An electromagnet is built using a 9-volt battery connected to a switch via conducting wire that is coiled around an iron nail. A pile of metal paper clips is moved close to the iron nail, yet no attraction is apparent between the electromagnet and the paper clips. What is the most likely conclusion to explain this result?(1 point) Responses There are not enough coils of wire around the iron nail. There are not enough coils of wire around the iron nail. The switch is turned off. The switch is turned off. The switch is turned on. The switch is turned on. The paper clips are made of a nonmagnetic metal.
The most likely conclusion to explain this result is: The switch is turned off.
