Grade 5 Physics Quiz: Magnetism and Static Electricity

Hannah, Ava, and Aiden are experimenting with magnets in their science class. They are trying to understand what a magnetic field is. Can you help them?

• A type of energy that repels metal objects

• A region around a magnet where the magnetic force is exerted

• The area where electricity is generated

• A type of force field that surrounds a magnet

During a science experiment, William and Benjamin noticed a magnetic field being created. Aria, who was observing, wondered how this was possible. What could have caused this?

• They were conducting the experiment during a lightning storm

• There was movement of electric charges

• The experiment was being conducted in sunlight

• They were rubbing two non-magnetic materials together

Arjun is working on a science project about electromagnets. He asks Mia and Oliver, 'What are electromagnets?'

• Oliver says, 'They are permanent magnets created by passing an electric current through a coil of wire wrapped around an iron core.'

• Mia says, 'They are magnets that are only attracted to wood and plastic.'

• Arjun's teacher says, 'They are magnets that are only created by rubbing a piece of iron with a magnet.'

• Arjun's dad says, 'They are temporary magnets created by passing an electric current through a coil of wire wrapped around an iron core.'

William is working on a science project about electromagnets. He wants to make his electromagnet stronger. What should he do?

• Decrease the number of coils in his electromagnet

• Increase the number of coils in his electromagnet or increase the current flowing through the wire

• Decrease the current flowing through the wire of his electromagnet

• Use a non-magnetic material for the wire of his electromagnet

Isla rubbed a balloon on her hair and then held it near James' hair. James' hair started to stand up. What is this an example of?

• The flow of electric current in a circuit

• The emission of light from a source

• The force of attraction between two objects

• Build-up of electric charge on the surface of objects

During a science experiment, Grace and Kai were rubbing two metals together, Ava was wearing synthetic clothing, and they noticed an imbalance of positive and negative charges. What could have caused this static electricity?

• Grace and Kai rubbing two metals together

• Presence of water vapor in the air

• Ava wearing synthetic clothing

• Imbalance of positive and negative charges

Arjun and David are studying about magnets in their science class. Their teacher asked, 'What are the two types of magnetic poles that a magnet has?'

• north pole and south pole

• positive pole and negative pole

• up pole and down pole

• east pole and west pole

Maya and Daniel are playing with magnets. What happens when they try to bring the same poles of their magnets together?

• The magnets become neutral

• The magnets attract each other

• The magnets explode

• The magnets repel each other

Harper, Liam, and Samuel are studying for their physics exam. They come across a question: 'What are electric charges?'. Samuel thinks it's the speed of light in a vacuum, Harper thinks it's the energy stored in a battery, and Liam thinks it's a physical property of matter that causes it to experience a force in an electromagnetic field. Who is correct?

• Samuel: The speed of light in a vacuum

• Harper: The energy stored in a battery

• Liam: Physical properties of matter that causes it to experience a force in an electromagnetic field

• None of them

Olivia and Ethan are studying for their physics exam. They are discussing the two types of electric charges. Mia overhears their conversation and says, 'Aren't they hot and cold?' Ethan disagrees and says, 'No, they are positive and negative.' Who is correct?

• Olivia

• Mia

• Ethan

• None of them
