Magnets

Question 1

Dipoles:

Answer 1

(magnets r made up of smaller magnets called dipoles) dipoles interact with other dipoles in the material

Question 2

What do dipoles do:

Answer 2

Line up in a single direction, then small magnetic domains are created (like tiny bar magnets)

Question 3

What do the domains do In a strong magnetic field ?

Answer 3

The small magnetic domains line up forming 1 large magnet with N&S poles

Question 4

What happens to the domains when u break a magnet in 2?

Answer 4

They form 2 magnets with N&S poles

Question 5

What happens when u disrupt the alignment of the domains so that he dipoles are randomly distributed?

Answer 5

They demagnetize

Question 6

Ferromagnetic materials:

Answer 6

Nickel , iron , cobalt, and alloys of them

Question 7

Electromagnetism:

Answer 7

(A combo of 2 words) electricity and magnet

Question 8

Oersteds principle:

Answer 8

Electricity moving through a conductor produces a circular magnetic field around the conductor

Question 9

Electron current flow:

Answer 9

(-) ——> (+)

Question 10

Conventional current flow:

Answer 10

(+) ——–> (-) (

Question 11

What does coiled wore do?:

Answer 11

It changes the field strength though constructed reinforcement

Question 12

What does a permeable core do?

Answer 12

Enhances the magnetic strength (depends on the type of core)
