Amplify Magnetic Fields Ch. 1 Flashcard

Front

What are the two poles of a magnet?

Back

A magnet has a north pole and a south pole.

Front

What happens to the magnetic field when a magnet is cut in half?

Back

Each half becomes a smaller magnet with its own north and south poles.

Front

What are magnetic domains?

Back

Tiny regions within a magnet where the magnetic fields of atoms are aligned in the same direction.

Front

What occurs at the poles of a magnet?

Back

Magnetic field lines are closest together, indicating the strongest magnetic force.

Front

How can a permanent magnet lose its magnetic field?

Back

By forcefully vibrating the object, causing its magnetic domains to fall out of alignment.

Front

What is an electromagnet?

Back

A type of magnet where the magnetic field is produced by an electric current.

Front

How can you strengthen an electromagnet?

Back

By increasing the current running through the wire or adding more coils.

Front

What is the relationship between electric current and magnetism?

Back

Electric current produces a magnetic field around the wire.

Front

Can magnetic field lines cross each other?

Back

No, magnetic field lines never cross.

Front

What materials can enhance an electromagnet's strength?

Back

Using a core made of ferromagnetic materials like iron, nickel, or cobalt.
