NGSS.MS-PS2-4

A material that allows electrons to flow freely from particle to particle

• Conductor

Magnetic fields and electric fields are identical in that they both–

• require a medium to travel from place to place.

• influence non-metals the same as metals.

• increase in strength with distance from source.

• are capable of exerting force at a distance.
