S8P5 Electricity & Magnetism

Front

What is the magnetic field of a magnet?

Back

The magnetic field is the area around a magnet where magnetic forces can be detected. It is strongest at the poles of the magnet.

Front

Where is the magnetic field of a magnet the strongest?

Back

The magnetic field is strongest at the poles of the magnet.

Front

What happens to two neutrally charged balloons when a positively charged rod is brought near one of them?

Back

Electrons on the balloons will move toward the rod, causing the balloons to become oppositely charged and move toward each other.

Front

What is charging by conduction?

Back

Charging by conduction occurs when two objects touch, allowing electrons to move from one object to another.

Front

What is charging by induction?

Back

Charging by induction occurs when a charged object is brought near a neutral object, causing a redistribution of charges within the neutral object without direct contact.

Front

What happens when a charged object comes into contact with an uncharged object?

Back

The charged object transfers some of its charge to the uncharged object, resulting in the uncharged object gaining a charge.

Front

What is the difference between positive and negative charges?

Back

Positive charges are created by a deficiency of electrons, while negative charges are created by an excess of electrons.

Front

What is the principle of electrostatic attraction?

Back

Electrostatic attraction occurs between oppositely charged objects, causing them to pull towards each other.

Front

What is the principle of electrostatic repulsion?

Back

Electrostatic repulsion occurs between like charges, causing them to push away from each other.

Front

What is friction in the context of charging?

Back

Friction is a method of charging where two objects are rubbed together, causing electrons to transfer from one object to another.
