Is magnetic flux the same as the magnetic feld?
magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.
What is the magnetic flux through the loop of a square wire loop 4Cm on a side which is perpendicular to the magnetic field 0.025Tesla?
The magnetic flux through the loop can be calculated using the formula: magnetic flux = magnetic field strength x area x cos(theta), where theta is the angle between the magnetic field and the normal to the surface. Since the loop is perpendicular to the magnetic field, theta = 0. The area of the square loop is 16 cm^2. Therefore, the magnetic flux through the loop is 0.025 Tesla x 16 cm^2 = 0.4 Weber.
How can the magnetic flux associated with coil or a closed circuit be changed?
A simple method for altering the magnetic flux would be to change the amount of current flowing in the coil or circuit. Generally speaking, more current, more magnetic flux, and vice versa.
What are lines of flux?
Flux is the presence of a force field in a specified physical medium, or the flow of energy through a surface.
Why does magnetic flux not pass through the hole in the washer?
This question refers to the phenomena of making a washer rise when it is in a superconducting state. This is a popular science demonstration experiment. Normal superconductors will not allow the penetration of a magnetic field into its interior. This is accomplished by creating a current distribution on the surface that is arranged to exactly cancel the externally created field in the interior of the superconductor. The induced current is an electromagnet and has an external magnetic field. As with any magnet, there is a force then between the electromagnet and the external magnetic field source. They repel and the washer moves.
What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
What does magnetic flux mean in physics?
Magnetic flux is a measure of the magnetic field through a given area. It quantifies the number of magnetic field lines passing through a surface. It is an important concept in electromagnetic theory and plays a crucial role in understanding magnetic phenomena.
When magnetic flux through surface is zero?
When the magnetic flux through a closed surface is zero, it means that the magnetic field lines entering the surface equal the field lines leaving it. This can occur when the surface encloses no magnetic sources or when it lies parallel to the magnetic field lines. Mathematically, it can be expressed as ∮B⋅dA = 0, where B is the magnetic field and dA is the differential area vector.
What is the direction of flux in a magnetic field?
The direction of flux in a magnetic field is perpendicular to both the magnetic field lines and the surface it passes through.
What is the formula for calculating the electric flux () through a closed surface?
The formula for calculating the electric flux () through a closed surface is EdA, where E is the electric field and dA is a differential area element on the surface.
What is the formula for magnetic flux and how is it calculated?
The formula for magnetic flux is B A cos(), where is the magnetic flux, B is the magnetic field strength, A is the area of the surface, and is the angle between the magnetic field and the surface normal. Magnetic flux is calculated by multiplying the magnetic field strength, the area of the surface, and the cosine of the angle between the magnetic field and the surface normal.
When magnetic flux through surface is maximum?
Magnetic flux through a surface is maximum when the direction of the magnetic field is in the same direction as the normal vector of the surface. In other words, the magnetic flux is maximum when the magnetic field is perpendicular to the surface area. That's why φ=BAcosθ, where θ is the angle between the direction of the magnetic field and the normal vector of the surface area. When the magnetic field is exactly the same direction as the normal vector (aka the magnetic field is perpendicular to the surface), θ=0 and cosθ = 1, its maximum value. The closer θ is to 90 degrees (ie. the more parallel the direction of the magnetic field is to the surface area, or the less parallel the magnetic field is to the surfaces normal vector), the smaller cosθ is, and thus flux will decrease accordingly.
Is magnetic flux the same as the magnetic feld?
magnetic field is a imaginary area around a manetic material where other magnetic subestences experience some force but flux is the imaginary lines of force that arise from magnet which indicate direction of force around it.
Is flux is directly proportional to charge?
Yes, according to Gauss's law, the flux through a closed surface is directly proportional to the charge enclosed by that surface. This is known as the electric flux theorem.
Why lenz's law can be applied only to closed loops?
Lenz's law and Faraday's law of Induction.The induced current causes a magnetic field according to Ampere's law, which itself has a flux through the closed loop. According to Lenz's law, the direction of the induced current and which results in the induced magnetic flux opposes the initial magnetic flux.
What is the relation between voltage and magnetic flux?
A magnet field is the area surrounding a magnet within which the effects of that field may be observed.A magnetic field is represented by imaginary lines of force that we call magnetic flux. Magnetic flux (symbol, the Greek letter phi) is measured in webers (pronounced 'vay-bers'); the intensity of the magnetic flux is called magnetic flux density which is defined as the flux per unit area, measured in webers per square metre, which is given the special name, the tesla.
How can one determine the electric flux through a surface?
To determine the electric flux through a surface, you can use Gauss's Law. This law states that the electric flux through a closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space. The formula for electric flux is E A cos(), where E is the electric field, A is the area of the surface, and is the angle between the electric field and the normal to the surface.
