Question

While researching magnetic fields, Marisa finds several online sites that describe a fictitious north monopole that is a magnet with only a north pole. Although it does not exist, the north monopole is used to describe magnetic field lines.

Which statement best describes how the monopole would be used to describe magnetic field lines?

A) The field lines around a magnet point from the south pole to the north pole to show the direction opposite to the magnetic force on the monopole.
B) The field lines around a magnet point from the south pole to the north pole to show the direction of the magnetic force on the monopole.
C) The field lines around a magnet point from the north pole to the south pole to show the direction opposite to the magnetic force on the monopole.
D) The field lines around a magnet point from the north pole to the south pole to show the direction of the magnetic force on the monopole.

Answer 1

A statement that best describes how the monopole would be used to describe magnetic field lines would be; D) The field lines around a magnet point from the north pole to the south pole to show the direction of the magnetic force on the monopole.

Answer 2

Answer: D) The field lines around a magnet point from the north pole to the south pole to show the direction of the magnetic force on the monopole.

Explanation:

A magnet has two poles: North pole and south pole. Monopole do not exist. In a magnet, domains of atoms oriented in a single direction exist. Magnetic field lines start from North pole and enter south pole.

If a monopole existed, it would be used to describe the magnetic field lines as the  field lines around a magnet point from the north pole to the south pole to show the direction of the magnetic force on the monopole.  Hence, the correct option is D.
