Strength of magnetic field in a current carrying conductor

Strength of magnetic field in a current-carrying conductor 

When an electric current is passed through a conductor a magnetic field is produced in the conductor. Current is supplied through Ac or dc power supply source, magnetic lines shown around the conductor that moves in a such way as starting from north and end at south of conductor. The direction of magnetic lines is as north to south. Electrons as magnetic property as the flow of charges is known as current in a similar way these same charges also create a magnetic field, which is also the property of atoms. There can be a permanent magnet to the current-carrying conductor. By introducing a permanent magnet there will be two magnetic fields one is inside the conductor and another outside as a permanent magnet by this way both fields interact with each other. The strength of the magnetic field depends upon the flow of current or supply of current to the conductor, length of the conductor, the material of the conductor, and the permanent magnetic field. These all factors lead to the create a strong field. If there is more flow current to the conductor, the magnetic field will be more strong and vice versa. Size, shape, and material of conductor also make strength in a magnetic field. Each material has a different magnetic property that depends upon the electrons. Then this leads to the structure, shape, and size of the conductor that also leads to creating strength in the magnetic field. A permanent magnet's field also contributes to the strength of the field. Here time also matters for the production of strong and uniform magnetic fields. How much current stays in the conductor and the other factors that make a duration for strengthening. Duration of these also leads to a strong field. The direction of the magnetic field, current direction, and motion in the conductor can be found by applying some rules like the right-hand grip rule for knowing the particular directions. When permanent magnet field and inside conductor's magnetic field interact in such a way which these creates motion in the conductor. The magnitude depends upon the angle between these fields. So the strength of the magnetic field in a current-carrying conductor depends upon this above factor that makes the strong fields. This is a basic principle of the magnetic field that acts in this way. This principle applies to many electrical appliances, machines, and electrical systems. This is the fundamental behavior of the conductor and magnetic field that leads to giant electrical and mechanical systems. 

Electronic material

Electronic materials are the electrical characterized material that contains different functionalities of electrical properties in electrical systems and circuit networks. There are different types of electronic materials. Electronic material is that material that consists of electrical strength, quality, and behavior. Each material has its characteristics and natures. Conductors, semiconductors, and insulators are electronic materials. These are the material used in electrical systems, networks, devices, circuits, etc. The behavior of electronic material depends upon the molecular structure and movements.  Each material has its characteristics and depends upon some factors. Resistance and current flow differ from each material (conductor, insulator, and semiconductors). Electronic materials are used to construct different applications. To construct and make our required electrical equipment, circuit, device, and anything else, we use these materials differently.  The behavior and function of this electronic material( conductors, semiconductors, and insulators) is as following:

Integrated circuits and electronic components consist of semiconductors, insulators, etc

Conductors:

Conductors have free movable electrons or charges to move and they can pass current easily because there are free electrons and resistance is low in the flow of current. The strength of the conductor depends upon the temperature, cross-sectional area of material, nature of the material, and length of the conductor. The relationship between the conductor's resistivity and temperature is linear. If the temperature increases, the resistivity of the conductor is also increased. This depends upon the molecular structure, when temperature increases motion of molecules increases and resistivity to current flow increases.

Copper conductor is used in electrical wire 

similarly, resistivity decreases when temperature decreases. If the length of the conductor increases, resistivity increases, and vice versa. Similarly when the conductor's cross-section area increases, the resistivity of conductor material decreases and vice versa. In conductors, there are different types of conductors that have different natures of material that differ from one to another. Each material has different resistivity, free electron, and current flow. Copper, gold, silver, aluminum, and iron, etc are the conductors.

Insulators:

Insulators are that electronic materials that have no free movable electrons or charges and possess high resistance. This insulator has the opposite functionality and behavior of the conductors. As insulators do not possess movable charges so they can not pass current. Inductors are the bad conductors. Due to the absence of electrons in insulators because there are no free available electrons to pass current so current is negligible in insulators. Like a conductor, an insulator also depends upon the same factors on which conductors depend. Temperature, cross-section area,

 length of material, and nature of the material. As the temperature increases, the resistance of insulators decreases and vice versa. By increasing the temperature the insulator can be converted into a conductor because the resistance decreases by the increase in temperature and then-current start to flow. Each insulators material has different insulating strength. Silicon,  rubber, glass, plastic, wood, etc are the bad conductors or insulators.

Semiconductors:

A semiconductor material has the function and behavior of both, conductor and insulators. Semiconductors are also called the intermediate form of material between conductor and insulator materials. Current can pass through semiconductors and resistance is moderate. If the temperature increases then resistance decreases and vice versa. Silicon, germanium, gallium arsenide, etc. Silicon is the best and most widely used semiconductor and it's also used in integrated circuits, electronic chips, and other electronic devices. Almost all the integrated circuits are made up of silicon and other semiconductor material. Electronic materials are the materials used in electronics, microelectronics, electrical network systems, and the substances for the building up of integrated circuits, circuit boards, communication cables, and various controlling and monitoring devices.

Fleming's right-hand rule

Force or motion of conductor, magnetic field, and current are perpendicular to each other(at a 90 degree)

Fleming's right-hand rule is the most convenient and easy way to find the directions of motion of conductor, induced current and magnetic field. The basic purpose of this rule is to find the direction of induced current when the conductor moves in a magnetic field. Fleming's right-hand rule applies to electric generators. Directions can be found by using our right hand with the thumb, forefinger, and middle finger.  According to Faraday’s law of electromagnetic induction. When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday's law of induction. The current in the wire can have two possible directions. Fleming's right-hand rule gives which direction the current flows. The right hand is held with the thumb, index, or forefinger, and the middle finger is mutually perpendicular to each other at right angles.

The thumb is pointing the direction of the motion of the conductor relative to the magnetic field. The forefinger is pointing in the direction of the magnetic field. Then the second finger represents the direction of the induced or generated current within the conductor. when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator's windings. This rule is used for electric generators.
