Electric, Magnetic, and Gravitational Field Review

Front

What is a magnetic field?

Back

A magnetic field is an invisible field around a magnet where magnetic forces can be detected. It is created by moving electric charges or by the intrinsic magnetic properties of materials.

What happens when two like poles of a magnet are brought together?

Back

They repel each other.

Front

What happens when two opposite poles of a magnet are brought together?

Back

They attract each other.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses. It pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, which can cause them to attract or repel each other.

Front

What is the principle of attraction and repulsion in electric charges?

Back

Like charges repel each other, while opposite charges attract each other.

Front

What is a compass and how does it work?

Back

A compass is a device that uses a magnetized needle to indicate direction. The needle aligns itself with the Earth's magnetic field, pointing towards magnetic north.

Front

What is the role of electric fields in the behavior of charged objects?

Back

Electric fields exert forces on charged objects, causing them to move or experience attraction or repulsion.

Front

What is the relationship between electric current and magnetic fields?

Back

An electric current flowing through a wire creates a magnetic field around the wire.
