if an object is attracted to magnet, the object is a magnetic material

1,3,4,6

A magnet attracts objects containing iron.

A magnet repels other magnets.

A magnet attracts other magnets.

A magnet aligns with Earth’s north pole.

A magnet is a source of magnetic field. Iron is a ferromagnetic material that has domains that get attracted due to magnetic force by a magnet. There are two poles on a magnet: North and south pole.

Unlike poles attract and like pole repel. So, two magnets can attract or repel depending on the orientation.

The magnetic South pole of Earth is at the geographical North pole. So, the magnet align with north pole i.e. north pole of magnet points geographical north.

The answer is A. Gravity

Explanation: Magnetic force is a force, like gravity, that is able to act across a distance without touching an object that is attracted by it. Magnetic attraction is a pulling force.

A

Explanation:

A

Explanation:

1st Qn) 1st option, the magnetic force of a magnet can act at a distance.

magnetism cannot be induced on the paper since paper is a non-magnetic material. In fact, the magnetic field can pass through the paper.

Gravity cannot attract the magnet to the door. Gravity only pulls things down towards the earth.

Magnetism does not involve the movement of atoms.

Q5) 3rd option, the iron filings lining up with the magnetic field lines

I've attached the diagram of how the iron filings look.

Note that although the filings are mostly concentrated at the poles of the magnets, they do not only accumulate there. Most of them are there as magnetic fields are stronger near the poles of the magnet.

Q8) 1st option, the magnetic attraction will decrease.

Q8) 1st option, the magnetic attraction will decrease.Q10) 1st option, wrap more coils around the nail.

Q8) 1st option, the magnetic attraction will decrease.Q10) 1st option, wrap more coils around the nail.Q11) 4th option, how the size of the magnet affects the strength of its magnetic pull on objects.

He used the same paper clip so he cannot be testing how the type of paper clip affects the way in which it reacts to the force of a magnet. For the same reason, option 3 I wrong too.

Q12) 2nd option, measure how close each magnet can get to a metal object before picking it up.

The mass of a magnet does not show its magnetic field strength.

4th option is simply measuring the volume of the magnets.

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.
