Movie Magic Lesson 1 Vocabulary

What is the flow of electric charge from one point to another within a circuit called?

• Force

• Levitation

• Electromagnet

• Electric current

Answer explanation

The flow of electric charge from one point to another within a circuit is called electric current. It is the correct choice because electric current refers specifically to the movement of charge in a circuit.

What is a type of magnet in which the magnetic field is produced by an electric current?

• Levitation

• Force

• Electromagnet

• Electric current

Answer explanation

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It is the correct choice because it is the only option that describes this type of magnet.

What is a push or a pull that causes an object to change its motion called?

• Levitation

• Force

• Electromagnet

• Electric current

Answer explanation

A force is a push or a pull that causes an object to change its motion.

What is a method by which an object is suspended or floats with no support called?

• Electric current

• Electromagnet

• Levitation

• Force

Answer explanation

Levitation is the method by which an object is suspended or floats with no support. It involves the use of forces to counteract gravity and achieve stability.

What is an object with a magnetic field that attracts magnetic objects towards it called?

• Twig

• Magnet

• Magnetic field

• Magnetic attraction

Answer explanation

A magnet is an object with a magnetic field that attracts magnetic objects towards it.

What is the ability of a magnet or magnetic field to pull objects of an opposite pole towards it called?

• Magnetic force

• Magnetic pole

• Magnetic field

• Magnetic attraction

Answer explanation

The ability of a magnet or magnetic field to pull objects of an opposite pole towards it is called magnetic attraction.

What is the area around a magnet where it attracts magnetic objects called?

• Magnetic field

• Magnetic attraction

• Magnetic pole

• Magnetic force

Answer explanation

The area around a magnet where it attracts magnetic objects is called the magnetic field.

What is a force (push or pull) that acts between magnets or moving electric charges called?

• Magnetic attraction

• Magnetic field

• Magnetic force

• Magnetic pole

Answer explanation

The force (push or pull) that acts between magnets or moving electric charges is called magnetic force. It is responsible for the interaction between magnetic materials and is the correct choice.

What is the end of a magnet, where its magnetic force is strongest, called?

• Magnetic attraction

• Magnetic field

• Magnetic pole

• Magnetic repulsion

Answer explanation

The end of a magnet, where its magnetic force is strongest, is called the magnetic pole. It is the correct choice because it is where the magnet's magnetic field is concentrated.

What is the ability of a magnet or magnetic field to exert a pushing force against objects which are of the same magnetic pole called?

• Magnetic field

• Magnetic attraction

• Magnetic repulsion

• Magnetic pole

Answer explanation

The ability of a magnet or magnetic field to exert a pushing force against objects of the same magnetic pole is called magnetic repulsion. It is the correct choice because it describes the phenomenon accurately.
