What are the two magnetic forces?
The most elementary force between magnets is the magnetic dipole–dipole interaction. If all of the magnetic dipoles that make up two magnets are known then the net force on both magnets can be determined by summing up all these interactions between the dipoles of the first magnet and that of the second.
Where is the force of a magnet the strongest?
The magnetic field generated by any magnet is always strongest at either pole. The magnetic force is equally as strong at both the north and south pole.
How many types of magnetic forces are there?
three types
What is magnetic force in simple words?
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
What is magnetic force Class 8?
Magnetic Force is a force that attracts certain metal objects (like iron and iron filings) towards a magnet. Electrostatic force is the force exerted by a charged body on another charged or uncharged body. Gravitational force is a force exerted by the earth on all objects on it.
What is a synonym for magnetic force?
Synonyms. attractive force electromagnetism attractive magnetism ferromagnetism antiferromagnetism paramagnetism attraction diamagnetism magnetic attraction.
How do you explain magnetic force to a child?
A magnet is a rock or a piece of metal that can pull certain types of metal toward itself. The force of magnets, called magnetism, is a basic force of nature, like electricity and gravity. Magnetism works over a distance. This means that a magnet does not have to be touching an object to pull it.
What are the 4 magnetic metals?

What is the strongest magnetic material?
neodymium
What objects do magnets stick to?
Magnets stick to metals that have strong magnetic properties themselves, such as iron and nickel. Metals with weak magnetic properties include aluminum, brass, copper and lead.
What is the most magnetic material in nature?
mineral magnetite
What are the only 3 things that can stick to a magnet?
What Kind of Objects Are Attracted to Magnets?
- Magnetic Elements: Metals. Iron, nickel and cobalt are strongly attracted to magnets.
- Magnetic Minerals. Certain minerals have attractions to magnetism, some weak, some very strong.
- Alloys: Metal Mixtures.
- Odd Everyday Things.
- Aurora Borealis.
What metal will a magnet not stick to?
Metals like brass, copper, zinc and aluminum are not attracted to magnets. Non-magnetic materials such as wood and glass are not attracted to magnets as they do not have magnetic materials in them.
What do you call a person who is magnetic?
alluring, attractive, captivating, charismatic, charming, enchanting, entrancing, fascinating, hypnotic, irresistible, mesmerizing, seductive. Antonyms. disagreeable, offensive, repellent, repulsive, unappealing, unattractive, unlikable or unlikeable, unpleasant.
What is it called when something is magnetic?
Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone.
What is another name for magnetic?

| transverse magnet | fridge magnet |
What are the 7 magnets?
What Are the 7 Types of Magnets
- Neodymium iron boron (NdFeB) – Permanent magnet.
- Samarium cobalt (SmCo) – Permanent magnet.
- Alnico – Permanent magnet.
- Ceramic or ferrite magnets – Permanent magnet.
- Temporary Magnets – magnetized in the presence of a magnetic field.
What is the opposite of a magnet?
The ends of a magnet are called its poles. One end is called the north pole, the other is called the south pole. If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other.
What is a synonym for magnetic personality?
SYNONYMS FOR magnetic 5 persuasive, charismatic, captivating.
What does it mean to have a magnetic personality?
In business, magnetism typically means being a center of influence. You’ve probably heard of a person having a magnetic personality. If something or someone is magnetic, the object or person has an extraordinary power or ability to attract. We tend to attract people most like ourselves in our daily encounters.
What does magnetic field mean in science?
Magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable.
What is the best definition of a magnetic field?
: the portion of space near a magnetic body or a current-carrying body in which the magnetic forces due to the body or current can be detected.
What is the cause of all magnetic fields?
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
What is B and H in magnetic field?
Answered 2 years ago. H is known as magnetic field intensity and B is known as magnetic flux density. and H is constant, and is only affected from its origin(might be a current carrying wire or a magnetic material) , ie even if the material inside which the flux is being calculated is changed, H remains constant.
