Electric Charge and Forces Flashcard

Front

What is an electromagnet?

Back

A temporary magnet whose magnetic field is produced by electrical current.

Front

What is a charged object?

Back

Matter with a surplus or deficiency of electrons.

Front

What indicates an increase in the strength of an electromagnet?

Back

If the electromagnet picks up more paper clips than before.

Front

What are the four factors that affect the size of an electromagnetic force?

Back

Distance, magnetic strength, current size, and force type.

Front

What happens when two like-charged balloons are rubbed with wool?

Back

They tend to move away from each other due to a non-contact force.

Front

What is the definition of electric charge?

Back

A property of matter that causes it to experience a force when placed in an electromagnetic field.

Front

What is the role of a battery in an electromagnet circuit?

Back

It provides the electrical current needed to create a magnetic field.

Front

What is the relationship between current and magnetic field strength in an electromagnet?

Back

Increasing the current increases the strength of the magnetic field.

Front

What is a non-contact force?

Back

A force that can act on an object without physical contact, such as magnetic or electric forces.

Front

What is the effect of distance on electromagnetic force?

Back

The electromagnetic force decreases as the distance between charged objects increases.
