The statement that accurately describes magnetic fields is:
A) Field lines are denser where the magnetic field is strongest.
This statement is true because the density of magnetic field lines represents the strength of the magnetic field; the closer the lines are to each other, the stronger the magnetic field in that region.
The other statements are incorrect:
- B) Magnetic fields are actually strongest near the poles of a magnet, not weakest.
- C) Field lines point from the north pole to the south pole of a magnet, not the other way around.
- D) Magnetic fields can affect not only charged particles but also other magnets and magnetic materials, so they don't only affect objects with charge.
