electric fields



Question 3

Bar magnets have ____ poles.


Question options:


1



2



3



4



Question 4

What elements have magnetic properties and will be attracted to magnets?


Question options:


Cobalt, sodium and mercury



Iron, cobalt, and nickel



Nickel, mercury and sodium



Sodium, cobalt and iron



Question 5

The movement or spinning of this subatomic particle is what creates magnetism.


Question options:


protons



Neutrons



electrons



quarks



Question 6

True or False: Magnets are weakest at their poles.


Question options:

True

False


Question 7

______________ are devices that create a magnetic field through the application of electricity.


Question options:


Motors



Electromagnets



Generators



Magnets


Question 8

True or False: Electromagnets are beneficial because they can be turned on and off.


Question options:

True

False


Question 9

The earth has a protective magnetic field around it, that is created by _________.


Question options:


the upward motion of mountain chains forming.



molten iron in the Earth's core.



molten iron in volcanoes.



the movement of tectonic plates.



Question 10

True or False: Doorbells, scrap yards, and rock concerts are all examples of every day uses of electromagnets.


Question options:

True

False


Question 11

True or False: Electromagnets cannot lift heavy objects.


Question options:

True

False


Question 12

Looking that following diagram of bar magnets, determine if the magnets will or will not connect (attract) and why.


barmagnet


Question options:


They will connect because the like poles are facing each other, and like poles attract.



They will connect because the different poles are facing each other, and different poles attract.



They will NOT connect because like poles are facing each other, and like poles repel each other.



They will NOT connect because different poles are facing each other, and different poles repel each other.


are my answers correct before I submit these:

1. unlike or different poles

2. magnetic fields

3. 2

4. Iron, cobalt, and nickel

5. electrons

6. False

7. Electromagnets

8. True

9. molten iron in the Earth's core.

10. True

11. False

12. They will NOT connect because like poles are facing each other, and like poles repel each other.

Answer:

different poles

Step-by-step explanation:

different poles attract to each other while same poles repel each other . just remember the old saying opposites attract and likes repel .

Answer: There are a lot of answers, so I will give a short answer to everyone:

1) The magnetic objects only come in dipolar form, so the poles attracted to each other are the different poles (negative to positive9

2) Magnets are surrounded by a field called Magnetic Field.

3) Bar magnets have two poles, as i already said, magnets commonly come in dipolar (two) forms.

4) Ferric materials, so the correct option is iron, cobalt, and nickel.

5) Electrons are the fundamental negative charges. Are the ones responsible of the electromagnetism (which includes the magnteism)

6) False, the magnetic field strength decreases as the distance to the source increases.

7) Electromagnets, as the name implies.

8) Turkish is actually the only benefit, the problem is that they need energy to work, so electromagnets are not actually beneficial for the environment.

9) by the molten iron in the Earth's core.

10) True, doorbells use magnetic fields to make a small piece of metal to vibrate and impact against metal to make noise, scrap yards are moved with big magnets, and the electric guitar and basses need electromagnetism to work, the pickups on those instruments have tiny magnets inside.

11) False, electromagnets do not have theoretical a limit on the magnetic field that they can create.

12) The diagram is missing.

The magnets will connect only if the poles that are facing each other are different.
