Magnets and Magnetic Field

Question 1

What is a magnet?

Answer 1

Any object that attracts the metal iron

Question 2

What are magnetic poles?

Answer 2

Place on a magnet where the force it applies is strongest

Question 3

Where is the magnetic force the strongest?

Answer 3

North and south poles

Question 4

When do magnets attract?

Answer 4

When opposite poles are near each other

Question 5

What happens when you cut a magnet?

Answer 5

Each piece of the broken magnet will create a north and south pole

Question 6

How does a magnet’s charge flow? (N-S or S-N?)

Answer 6

North to south

Question 7

What is the area around a magnet called?

Answer 7

Magnetic field

Question 8

How does a compass work?

Answer 8

A compasses needle needs to always align with the magnetic field lines of a magnet

Question 9

What are magnetic domains?

Answer 9

Magnetic domain is when atoms form groups in magnetic material

Question 10

How are magnetic domains organized in a magnet?

Answer 10

North/north, south/south

Question 11

What are ferromagnetic materials?

Answer 11

Give examples. Elements including iron, nickel and cobalt that have an especially strong attraction to magnets

Question 12

What are permanent

Answer 12

Permanent magnets are magnets that remain a magnet after being removed from another magnetic field

Question 13

What are temporary magnets?

Answer 13

Temporary magnets are magnets that quickly lose its magnetic field after being removed from a magnetic field.

Question 14

What are the three parts of an atom? What charges do they have?proton/positive…electron/negative….neutron/neutral

Answer 14

Proton, neutron, electron

Question 15

What charges do Proton, neutron, electron have?

Answer 15

proton/positive…electron/negative….neutron/neutral

Question 16

What part of the atom can move to another object? What are the “rules” for this?

Answer 16

Electrons can move,

Question 17

How is an atom similar to a magnet?

Answer 17

Positive and negatively charged objects can attract each other. Two negatively charged repel each other. Two positively charged repel each other

Question 18

When is an atom positively charged?

Answer 18

When an object loses electrons it is more positively charged

Question 19

When is an atom negatively charged?

Answer 19

When an object gains electrons has a negative charge

Question 20

What is friction?

Answer 20

Friction is a contact force that resists a slidubg motion of two surfaces that are touching. Give an example of how it helps transfer electrons.

Question 21

What is static electricity? Static Charge?

Answer 21

An unbalanced negative or positive charge on an object

Question 22

What is static discharge?

Answer 22

Static discharge is the release of static electricity when two objects touch.

Question 23

What is an electrical conductor? Materials in which electrons can easily move Insulators?

Answer 23

A material in which electrons can not easily move through

Question 24

Examples of conductors?

Answer 24

Most metals, copper, aluminum.

Question 25

Examples of insulators?

Answer 25

Glass, rubber, wood, air

Question 26

What is Gravity?

Answer 26

Gravity is a force which tries to pull two objects toward each other

Question 27

What factors affect the amount of gravitational force?

Answer 27

Mass and distance

Question 28

How is weight changed by distance?

Answer 28

The closer to the object the greater the pull towards that object
