Both electric charges and magnetic poles are of two types, the force acting between them is similar. Like poles repel each other and unlike poles attract each other. The lines of forces in magnetism and static electricity initiate from one pole or charge and end into the other.
What are like charges and like poles?
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.
Both have a charge of magnitude e = 1.602 × 10-19 Coulombs. Opposites attract, and likes repel; two positive charges placed near each other will repel, or experience a force which pushes them apart. The same is true of two negative charges. A positive and a negative charge, however, will attract each other.
How are charges poles and fields related?
Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract. Electric field points in the direction of the force experienced by a positive charge.
Both magnets and charges have poles. Both opposites attract and likes repel. Electric charges can be isolated, but magnetic poles cannot. Charges can be positive or negative; magnets have north and south poles.

The difference between a motor and a generator is that a generator turns mechanical energy to electrical energy, and a motor turns electrical energy to mechanical energy.
What is the basic difference between an electric generator and an electric motor?
An electric motor converts electricity into mechanical energy, providing a power source for machinery. A generator does the opposite of this, converting mechanical energy into electricity.
What is difference between electric field and charge?
Electric charge is something that a particle/ object has due to excess/deficent charge present on it. Electric field is the magnitude of Electrostatic force experienced by an electricaly charged particle in space.
How are electric charges and magnetic fields related?
Both electric and magnetic fields are the consequence of the attraction and repulsion of electric charges. However, a magnetic effect is caused by moving electric charges while an electric field is caused by stationary charges.
What are the similarities between magnetic circuit and electric circuit?
What is the difference between electromagnets and bar magnets?
Hint The basic difference between them is that a bar magnet is a permanent magnet whereas an electromagnet is a temporary magnet. An electromagnet is formed when an electric current is passed through wires wound around soft metalcore. An electromagnet loses its magnetism once the current flow is stopped.
How are electromagnets similar to other magnets How are electromagnets different from other magnets?
The difference between a permanent magnet and an electromagnet is as follows: Permanent magnets are permanently magnetized while electromagnets are temporarily magnetized. The former is made up of hard materials while the latter one is made up of soft materials.
How are electromagnets different than regular magnets?
The key difference between an electromagnet and a permanent magnet is that the electromagnet can have a magnetic field when an electric current flows through it and disappears when the flow of the current stops, while permanent magnets are made up of magnetic material that can be easily magnetized and can create its …
What are the similarities of electric potential and electric potential energy?
What is the relation between electrical energy charge and Potential difference?
Electric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy experienced by a test charge that has a value of +1 .
What is the difference between potential energy of a charge at a certain point and the potential at that point?
The basic difference between electric potential and electric potential energy is that Electric potential at a point in an electric field is the amount of work done to bring the unit positive charge from infinity to that point, while electric potential energy is the energy that is needed to move a charge against the …
What are the similarities and differences between electric motor and generator?
What is the basic difference between electric and magnetic lines of?
Answer. Electrical field lines induces on a positive charge and diminishes in a negative charge whereas a magnetic field line starts at the north pole and ends at the south pole. Electric field and magnetic field lines are mutually perpendicular to each other.
What is the difference between electricity and electromagnetism?
Key Takeaways: Electricity and Magnetism A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current. In an electromagnetic wave, the electric field and magnetic field are perpendicular to one another.
Where is the motion of electric charges in a common bar magnet?
With a typical bar magnet, for example, the field goes from the north pole to the south pole outside the magnet, and back from south to north inside the magnet. Electric fields come from charges. So do magnetic fields, but from moving charges, or currents, which are simply a whole bunch of moving charges.
How two different bar magnets with north and south poles interact with each other?
North and south poles of two magnets attract each other, while two north poles or two south poles repel each other. A magnet can exert force over a distance because the magnet is surrounded by a magnetic field. In the Figure below, you can see the magnetic field surrounding a bar magnet.
Why are magnetic materials attracted to magnets?
You may have noticed that the materials that make good magnets are the same as the materials magnets attract. This is because magnets attract materials that have unpaired electrons that spin in the same direction. In other words, the quality that turns a metal into a magnet also attracts the metal to magnets.
In what way is the rule for the interaction between magnetic poles similar?
How is the rule for the interaction between magnetic poles similar to the rule for the interaction between electrically charged particles? Like poles repel, unlike poles attract, and the force is proportional to the inverse square of the distance between two poles.
How do magnetic and electric fields differ quizlet?
How do they differ? A magnetic field can be modeled using magnetic lines of force. Electric fields begin at a positive charges and end at negative charges.
What is the difference between the fields surrounding a stationary charge and those that surround a moving charge?
1 Answer. Around a stationary charge there is only an electric field, but the moving charge will also have produce a magnetic field (while still having the electric field).

Is an iron nail more attracted to the north or south pole of a magnet?
When an object such as iron nails is brought close to the magnet and when it enters the field of the magnet, the magnet tends to develop the magnetism in the iron nails which results in the attraction and hence it sticks with the magnet. If an iron nail is attracted towards a north pole of the magnet and sticks to it.
