The diagram of the working principle of scrap heap magnet is in the image uploaded.
The scrap heap magnet is a complex or large electromagnet that is powered by a very large battery.
The working principle of a scarp heap magnet is the same as an ordinary electromagnet. The thick insulated copper wire is wound around a soft iron core. When current is allowed to pass through, it becomes very strong and attracts all the magnetic materials in the scrap.

Answer:
An idea, event, or object can be represented by a 'model' to help people better understand it.
Explanation:
If an idea, event or object is to be represented or introduced to an individual or a group of people, a good idea is to represent it with a model.
The reason behind it being that a model will help the people understand it better as they will be able to see something in front of it and know what is being discussed.
The lithosphere is made up of the Earth's crust and the upper part of the mantle. It is responsible for the formation of landforms like mountains and plateaus.
The lithosphere is made up of the Earth's crust and the upper part of the mantle. The Earth's crust is divided into several tectonic plates that float on the semi-fluid asthenosphere underneath. This rigid lithosphere is responsible for the formation of landforms like mountains, valleys, and plateaus.

2)the needle of compass line up with earth magnetic field and point to_________
a)earth poles b)earth equator
3)magnetic field lines that curve toward each other show_________
a)repulsion b)attraction
4)some animals have tiny pieces of ___________in their brains to help them find their way
a)magnetite b)magnetosphere
5)a magnet contain a large number of magnetic _____that are lined up and pointed in the same direction.
a)domains b)poles
Answer:
1 . a) the poles
2. a) earth poles.
3. b) attraction.
4. a) magnetite.
5. a) domains.
Explanation:
The magnetic field is strongest at the poles and very weak at the center of the magnet.
The magnetic compass will always align along the north - south poles of the earth. North of the compass needle is attracted towards the magnetic south pole of the earth.
Magnetic Field lines begin at the north pole of the magnet and end at the south pole. Unlike poles attract and like poles repel , so they curve for unlike poles.
Magnetite is a magnetic mineral, which is present in the animal brains , enabling them to identify correct directions.
Magnetic domains are regions where individual magnetic moments of the atoms are aligned in a definite direction.
Answer:
Explanation:
There are two major types of mixtures; homogeneous and heterogeneous mixtures.
Homogeneous mixture is a mixture in which its constituent particles are evenly distributed throughout the mixture. Examples are steel, bronze and air (as stated in the question). While heterogeneous mixture is a mixture in which it's constituent particles are not evenly distributed throughout the mixture. Example includes sand and water solution.
Salt water is an homogeneous mixture because the percentage of salt in a sample of salt from a particular mixture is the same in every other sample (of the same volume) of the same mixture.
From the above, we can deduce that air is an homogeneous mixture because a sample of air (in a particular area) will contain the same constituent by proportion as another sample of air (in the same area). This means that the percentage of oxygen, nitrogen, carbon dioxide, water vapour, argon and other substances in one sample of the air will be equal to the percentage of this constituents in the other sample of the air.
Same can be said about steel and bronze. For steel, each gram of the same steel will contain the same percentage of carbon and iron. And also, each gram of the same bronze will contain the same percentage of copper, tin and other metals present.
For better understanding, let's consider an heterogeneous mixture. A mixture of sand and water solution cannot have the same proportion throughout, this is because sand particles in some samples (of a particular volume) of a particular mixture will be different from sand particles in some other samples (of the same volume) of the same mixture.
