Question

this model represents the magnetic field between two bar magnets.
determine whether each statement is true or false.
statement | true | false
the magnets repel each other. | |
the magnetic field lines point in the direction of the force that the north pole of a magnet would feel. | |
a magnetic material would be repelled by the north poles of the magnets. | |
the magnetic field is strongest very close to the poles of the magnets. | |

Explanation:

Step1: Analyze "The magnets repel each other."

Magnetic field lines between two magnets: like poles repel (N-N or S-S), unlike attract (N-S). Here, left magnet's N faces right magnet's N (both red ends are N). So field lines between them push apart, meaning repulsion. So this statement is True.

Step2: Analyze "The magnetic field lines point in the direction of the force that the north pole of a magnet would feel."

By definition, magnetic field lines' direction is the direction a north magnetic pole would experience a force (north pole moves along field lines, south pole opposite). So this is True.

Step3: Analyze "A magnetic material would be repelled by the north poles of the magnets."

Magnetic materials (like iron) are attracted to both poles (north and south) of a magnet, not repelled. Repulsion is for like magnetic poles, but magnetic materials are ferromagnetic and get attracted. So this is False.

Step4: Analyze "The magnetic field is strongest very close to the poles of the magnets."

Magnetic field strength is highest near the poles (field lines are densest there, indicating stronger field). So this is True.

Answer:

• "The magnets repel each other.": True
• "The magnetic field lines point in the direction of the force that the north pole of a magnet would feel.": True
• "A magnetic material would be repelled by the north poles of the magnets.": False
• "The magnetic field is strongest very close to the poles of the magnets.": True

(For each statement, mark the corresponding "True" or "False" circle. The above are the truth values for each.)
