Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction.

Front

What happens when two like charges are brought together?

Back

Two like charges (e.g., two positively charged objects) will repel each other.

Front

What is the cause of Earth's magnetic field?

Back

Earth's magnetic field is caused by moving currents of molten iron and nickel interacting with Earth's iron core.

Front

How can an iron nail become a permanent magnet?

Back

An iron nail can become a permanent magnet by being stroked many times with a permanent magnet.

Front

What is friction in the context of charge transfer?

Back

Friction is a method of charge transfer where electrons are transferred between two objects when they rub against each other.

Front

What is induction in terms of charge?

Back

Induction is the process of charging an object without direct contact, often through the influence of a nearby charged object.

Front

What is contact in the context of charge transfer?

Back

Contact is the transfer of charge that occurs when two objects touch each other.

Front

What is a magnetic field?

Back

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

Front

What happens when a north pole of one magnet approaches the north pole of another magnet?

Back

The north poles will repel each other.

Front

What is a magnetic domain?

Back

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