Magnets and Static Electricity Quiz

What is the property of a material that allows it to attract iron objects?

• Electromagnetism

• Non-magnetism

• Ferromagnetism

• Static electricity

What is the difference between a permanent magnet and a temporary magnet?

• A permanent magnet loses its magnetism once it is magnetized, while a temporary magnet retains its magnetism indefinitely.

• A permanent magnet retains its magnetism once it is magnetized, while a temporary magnet only retains its magnetism for a limited time.

• A permanent magnet is used in electromagnets, while a temporary magnet is used in MRI machines.

• A permanent magnet is made of steel, while a temporary magnet is made of copper.

How does static electricity occur?

• Exposure to direct sunlight

• Friction between two non-electrically charged objects

• Imbalance of electric charges on the surface of an object

• Presence of water on the surface of an object

What is the difference between conductors and insulators?

• Conductors allow the flow of electricity, while insulators do not.

• Conductors are used for cooking, while insulators are used for heating.

• Conductors allow the flow of water, while insulators do not.

• Conductors are transparent, while insulators are opaque.

What is the role of electrons in static electricity?

• They attract protons in static electricity

• They repel other electrons in static electricity

• They have no role in static electricity

• They create static electricity when they move from one object to another.

What is the difference between a positive charge and a negative charge?

• Excess of neutrons in positive charge and excess of protons in negative charge.

• Excess of protons in positive charge and excess of neutrons in negative charge.

• Excess of protons in positive charge and excess of electrons in negative charge.

• Excess of electrons in positive charge and excess of protons in negative charge.

How can you create a temporary magnet?

• By stroking a piece of iron or steel with a permanent magnet.

• By rubbing a piece of iron or steel with sandpaper

• By exposing a piece of iron or steel to water

• By heating a piece of iron or steel

What are the properties of a magnet?

• Lack of a north and south pole

• Ability to generate electricity

• Attraction to other magnets and magnetic materials, ability to repel other magnets, and presence of a north and south pole

• Inability to attract any materials

What are some examples of static electricity in everyday life?

• Rubbing a cat on your hair

• Using a vacuum cleaner

• Lighting a candle

• Rubbing a balloon on your hair, walking across a carpet and getting a shock when touching a metal doorknob, lightning during a storm

How can you demagnetize a magnet?

• Expose it to sunlight

• Rub it with a cloth

• Heat it to a high temperature or subject it to a strong magnetic field in the opposite direction

• Drop it in water
