Magnetism (7th Grade Science)

Front

What is magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be detected.

Front

What are magnetic poles?

Back

Magnetic poles are the two ends of a magnet where the magnetic force is strongest; they are labeled as north (N) and south (S).

Front

What happens when unlike magnetic poles are brought together?

Back

Unlike magnetic poles attract each other.

Front

What happens when like magnetic poles are brought together?

Back

Like magnetic poles repel each other.

Front

What is a magnetic domain?

Back

A magnetic domain is a region within a magnetic material where the magnetic moments of atoms are aligned in the same direction.

Front

What is solar wind?

Back

Solar wind is a stream of charged particles released from the upper atmosphere of the sun.

Front

What is an aurora?

Back

An aurora is a natural light display in the Earth's sky, predominantly seen in high-latitude regions, caused by the interaction of solar wind with the Earth's magnetic field.

Front

What is the magnetosphere?

Back

The magnetosphere is the region of space surrounding the Earth that is dominated by Earth's magnetic field.

Front

What is the difference between attraction and repulsion in magnetism?

Back

Attraction occurs when unlike poles come together, while repulsion occurs when like poles push away from each other.
