planetary forces?
distinguishing electricity and magnetism
consider the properties of electric charges and magnets shown in the following
list. write each property beneath the appropriate description in the chart.
properties:

• produces a field that can apply forces to objects
• can apply an attractive or repulsive force
• has a north and south pole
• is responsible for the behavior of lightning
• can have a positive or negative charge
• is responsible for the behavior of a compass

properties of electric charge | properties of a magnet | properties of both

Explanation:

• Electric charge properties: Lightning is caused by static electric discharge; electric charges have positive/negative signs.
• Magnet properties: Magnets have north/south poles; compasses align with Earth’s magnetic field.
• Both properties: Electric fields and magnetic fields exert forces on objects; both can attract/repel (charges: like repel, opposite attract; magnets: like poles repel, opposite attract).

Answer:

Properties of a Magnet	Has a north and south pole<br>Is responsible for the behavior of a compass
Properties of Both	Produces a field that can apply forces to objects<br>Can apply an attractive or repulsive force
