Question
If you take a bar magnet with both N & S poles and cut it in half, you get
A) one magnet with an N pole only, one magnet with an S pole only
B) two magnets, each with N & S poles
C) two non-magnets
2.
A magnetic dipole (such as a compass needle) wants to
A) align with the magnetic field
B) align with the electric field
C) lie opposite the magnetic field
D) lie opposite the electric field
E) be perpendicular to the magnetic field
F) be perpendicular to the electric field
3.
Magnetic field lines
A) exit + charges and enter - charges
B) exit N poles and enter S poles
C) are always perpendicular to the E field lines
D) are always perpendicular to the equipotentials
E) exit S poles and enter N poles
F) exit - charges and enter + charges

Explanation / Answer
If you take a bar magnet with both N & S poles and cut it in half, you get
B) two magnets, each with N & S poles
The poles of a magnet can not be separated, by dividing the particles are rearranged in more halves and create a new magnet.
2.
A magnetic dipole (such as a compass needle) wants to
A) align with the magnetic field
the magnetic field vector is character, and aligned, same as a needle with the magnetic field of the earth,
3.
Magnetic field lines
B) exit N poles and enter S poles
This established that in a magnet the magnetic field lines run from the north pole, and reach the south pole
