Increase or Decrease
100
A physical property of matter that leads to electric and magnetic interactions
What is an electric charge?
100
An object that attracts materials that contain iron
What is a magnet?
100
The area in which a force that acts from a distance can be detected.
What is a field?
100
A measure of the pull of gravity on a mass
What is weight?
100
Getting closer to our source will do this to our non-contact force.
What is increase the force?
200
These types of charges repel one another
What are like charges?
200
Areas where the poles of groups of atoms line up in the same direction
What is magnetic domains?
200
What is an electric field?
200
Objects in space are held in this path by gravity
What is an orbit?
200
This property, besides distance, affects our electric force.
What is magnitude of electric charges?
300
An object that has an equal amount of positive and negative charges
What is a neutrally-charged object?
300
The interaction between electricity and magnetism

300
This can be done to increase our electromagnetic force without changing our battery.
What is increase the number of loops?
400
A continuous flow of electric charges from one region to another
What is electric current?
400
Occurs when a current is generated by a changing magnetic field
What is electromagnetic induction?
400
This type of field only attracts.
What is gravitational field?
400
These objects have very large gravities and are lightyears in diameter
What is a galaxy?
400
This can be done to increase our electromagnetic induction without replacing our magnet or changing the number of loops.
What is increase the speed of the magnet?
500
This can be used to measure electric current?
What is an ammeter?
500
Doing this to a magnet can make it lose its magnetic force
What is unaligning the magnetic domains?
500
A compass can be used to show this kind of field
What is a magnetic field?
500
An object experiences a horizontal velocity and a vertical gravity
What is projectile motion?
500
A loss of mass in the sun would do this to the Earth
What is decrease the gravitational force between the sun and the Earth
