Question:

Why do only a few materials show magnetic properties?

All atoms act like tiny magnets. Why do only a few materials show magnetic properties? a.Magnetic materials have atoms that are much stronger magnets than the atoms of other materials.b.Atomic magnets are magnified when combined with a rare substance. Magnetic materials contain this rare substance.c.We see magnetic properties only if atomic magnets line up with Earth‘s geographic south and north poles. In magnetic materials this arrangement can occur.d.We see magnetic properties only if atomic magnets line up in the same direction throughout a material. In magnetic materials this arrangement can occur.

Answer:

Ask at dealerships as they have the pamphlets already printed out.
Gust buy a AWD and cover your bases.
D of course. Each orbiting electron can be modeled by an equivalent current loop (a magnetic dipole). If these dipoles are lined up then they produce a magnetic field.
