Magnets (Part 1)
A type of magnet in which the magnetic field is produced by an electric current
Electromagnet
A magnetized object that creates its own magnetic field that is always on
Evidence for a lot of energy in this energy store would be an object in motion
Kinetic Store
The amount of matter in an object, measured in kilograms
Mass
A natural phenomenon by which all things with mass are brought toward one another
Gravity
The ability of a magnet or magnetic field to pull objects of an opposite pole towards it
Magnetic Attraction
The end of a magnet, where its magnetic force is strongest (there are north and south)
Magnetic Pole
Evidence for a lot of energy in this energy store would be when the temperature is high
Thermal Store
Fill in the blank:
________ is a measure of the force of gravity on the matter of an object (measured in Newtons)
Weight
The force that pushes electrons through a circuit to produce electricity
Voltage
The area around a magnet where it attracts magnetic objects
Magnetic Field
The ability of a magnet or magnetic field to exert a pushing force against objects which are of the same magnetic pole
Magnetic Repulsion
Evidence for only a little energy in this energy store would be when an object is very close to the Earth's surface
Gravitational Potential Store
As an object gets further from a planet, the gravitational pull on the object will __________.
Decrease
The flow of electric charge from one point to another within a circuit
Electric Current
A push or pull that acts between magnets or moving electric charges
Magnetic Force
A method by which an object is suspended, or floats, with no support
Levitation
Evidence for a lot of energy in this energy store would be when a rubber band is stretched
Elastic Store
Choose the largest number:
A. 3.92 x 10^23
B. 4.61 x 10^24
C. 1.92 x 10^25
C
The force exerted by a magnet when it attracts or repels other magnetic material
Magnetism
The force of an object's magnetic field, which determines how much force it can exert on other objects
Magentic Strength
What are two ways you can strengthen an electromagnet?
1. Add more coils
2. Increase voltage (add more batteries)
Evidence for a lot of energy in this energy store would be an explosion
Chemical Store
A basic force, such as gravity, that affects how objects or particles interact
Universal Force
A push or a pull that causes an object to change its motion (that is, start moving, stop moving, or change direction)
Force
