How do you find the magnetic flux through a loop?
The magnitude of the induced emf can be calculated using Faraday's law.
- The magnetic field inside the long coil is B = μ0(N/ℓ)I.
- The flux through the coil is NBA = μ0(N2/ℓ)IA.
- The change in flux per unit time is μ0(N2/ℓ)A ∆I/∆t = L*∆I/∆t, since I is the only quantity changing with time.

What is the magnetic flux through the coil?
Change in the number of field lines through a coil gives a current. Number of field lines through a coil is called magnetic flux. When a loop is moved parallel to a uniform magnetic field, there is no change in the number of field lines passing through the loop and no induced current.
How do you calculate flux?
Find the flux of F=yˆj−zˆk through the paraboloid S=y=x2+z2,y≤1. The flux can be described by ∬SF⋅ndσ with n=2xˆi−ˆj+2zˆk√1+4×2+4z2. Substitute x2+z2=y to simplify n to −1+2z2y. The total flux through the surface is 0.
How is magnetic flux measured?
Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics, that evaluates the change of voltage in the measuring coils to calculate the measurement of magnetic flux.
What unit is magnetic flux?
Weber (Wb) The SI unit of magnetic flux is the Weber (Wb). A flux density of one Wb/m2 (one Weber per square metre) is one Tesla (T).
What is magnetic field equation?
The magnitude of the force on a wire carrying current I with length L in a magnetic field is given by the equation. F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current.
What is magnetic flux units?
The SI unit of magnetic flux is the Weber (Wb). A flux density of one Wb/m2 (one Weber per square metre) is one Tesla (T). Weber is commonly expressed in a multitude of other units. W b = k g . m 2 s 2 .
How do you find the direction of induced current in a loop?
By Lenz law, we know that the direction of the induced magnetic field will be in a direction such that it opposes any change in the flux. Once we know this direction, we can make use of Fleming's right-hand rule, to find the direction of the induced current by pointing the thumb in the direction of the magnetic field.
What is the value of the magnetic flux through the coil in Figure 23.56 B due to the wire?
zero flux Figure 23.56(b) There is zero flux since the magnetic field lines due to the current are parallel to the plane of the coil.
What is total magnetic flux?
Magnetic flux is a measurement of the total magnetic field which passes through a given area. It is a useful tool for helping describe the effects of the magnetic force on something occupying a given area. The measurement of magnetic flux is tied to the particular area chosen.

How do you calculate flux in math?
Formulas for calculating flux
- To calculate flux through a surface we can use the formula ∫∫SF⋅(Tu×Tv)dA.
- However using Stokes' Theorem we can also calculate flux using ∫∫S(∇×F)⋅dS.
- These are not equal because ∫∫SF⋅(Tu×Tv)dA=∫∫SF⋅dS.
