What is magnet and its properties?
A magnet is a material or artificial setup that can produce a magnetic field around it. Due to the magnetic field, a magnet can attract ferromagnetic materials (e.g. iron filings) and attract or repel any other magnet. Magnets, suspended through a string, always point towards the north-south direction.
What is the property of magnetic materials?
Explanation: Magnetic materials have the property of retentivity in which the magnetic flux produced acts according to the external magnetic field. When the external field is removed, the magnetization in the materials doesn't deform immediately.

What are the properties of a magnet for kids?
The three properties that all magnets have are that they all attract (or stick to) certain metals, they have north and south poles (ends), and two of the same poles will repel (or push away from) each other, while opposite poles will be attracted to each other.
What are two properties of magnets?
Solution: Attractive property – A magnet attracts small pieces of iron, cobalt or nickel. Directive property – A magnet when suspended freely, always points towards north and south directive.

List of Properties of Magnet:
- Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
- Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
- Directive Property – A freely suspended magnet always points in a north-south direction.
What are the 3 examples of magnetic materials?
Iron, Nickel, and Cobalt are the magnetic substances as objects made up of these materials are attracted by a magnet. Also, magnetic materials can be magnetized or we can say that magnetic materials can be converted into magnets.

What are the three main properties of air?
The properties of air are:
- Air is a mixture of many gases, water vapours and dust particles.
- Air exerts pressure.
- Air has mass.
- Air occupies space.
- Air is colourless and odourless.
What three ways can the strength of an electromagnet can be increased?
The three ways by which the strength of an electromagnet can be increased are:
- By increasing the current flowing in the coil.
- By increasing the number of turns in the coil.
- By inducing the length of the air gap between the poles.
How is Earth like a magnet?
The crust of the Earth has some permanent magnetization, and the Earth's core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a "magnet."
What is magnetic properties in simple words?
The magnetic property of a material is the atomic or subatomic response a material to an applied magnetic field wherein the electron spin and charge create a dipole moment and a magnetic field.
What are the three properties of matter?
There are three common states of matter:
- Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other. …
- Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded. …
- Gases – no definite volume or shape.
What are three properties of acids?
These properties are:
- Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current. …
- Acids have a sour taste. …
- Acids change the color of certain acid-base indicates. …
- Acids react with active metals to yield hydrogen gas. …
- Acids react with bases to produce a salt compound and water.

What is solenoid How is it different from coil?
A coil is a normal bundel of wire wrapped circularly, whereas a solenoid is the circular coil of insulated wire which acts as a magnet when electric current flows through it.
What is magnet made of?
Magnets are made of a group of metals called ferromagnetic metals. Nickel and iron are examples of these metals. Metals such as these are unique in their ability to be magnetized uniformly.
Is the sun a magnet?
Measuring Magnets Similar to our own planet, the sun is like a huge bar magnet with a north and a south pole producing a magnetic field. But the sun's magnetic field is about twice as strong as the Earth's and much, much larger, extending well beyond the farthest planet in the solar system.
What are four examples of properties?
Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.
What are the properties of metal?
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).
What are 3 properties of base?
General Properties of Bases
- Bases release a hydroxide ion (OH–) into water. The more ions that are released the stronger the base.
- Bases react with acids. When an acid and a base react, they form water and a substance called a salt.
- Bases turn red litmus blue.
