When the area of a loop of wire is perpendicular to the magnetic field the magnetic flux is?
When calculating the magnetic flux we include only the component of the magnetic field vector which is normal to our test area. In the case that the surface is perpendicular to the field then the angle is zero and the magnetic flux is simply B A B A BA .
How do you find the magnetic flux through a solenoid?
This field is producing a maximum magnetic flux through the coil as it is directed along the length of the solenoid. Therefore, the magnetic flux through the coil is the product of the solenoid's magnetic field times the area of the coil.
What is the magnetic flux in the loop?
The magnetic flux (Φ) threading a conducting loop as a result of current in the loop is directly proportional to the current (I). (35.4) The constant of proportionality L is called the self-inductance of the loop. A changing current in a conducting loop creates a changing magnetic flux within the loop.

Why is magnetic flux zero in a closed surface?
Magnetic flux through a closed surface is zero because the field lines entering the surface is equal to the field lines leaving the surface.
What is the magnetic field due to a solenoid?
The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length. There is no dependence on the diameter of the solenoid, and the field strength doesn't depend on the position inside the solenoid, i.e., the field inside is constant.

What is induced when the magnetic flux through the loop changes?
An electric current can be induced in a loop by a changing magnetic field. This would be the current in the secondary circuit of this experimental set-up. The induced current exists only while the magnetic field through the loop is changing. magnetic field.
How do you calculate 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.
Is magnetic flux perpendicular?
Magnetic flux is the product of the average magnetic field times the perpendicular area that it penetrates. It is a quantity of convenience in the statement of Faraday's Law and in the discussion of objects like transformers and solenoids.
What is the magnetic flux through an open surface?
While the magnetic flux through a closed surface is always zero, the magnetic flux through an open surface need not be zero and is an important quantity in electromagnetism.
Is the flux through a closed surface always zero?
The flux of a vector field through a closed surface is always zero if there is no source of the vector field in the volume enclosed by the surface.
What is magnetic field due to a current through a circular loop?
Magnetic field due to current in a circular loop depends on Hence, the field produced will be same in magnitude in direction. Therefore, the field in each turn adds up. Hence, if there are n turns, there will be n current carrying loops, and the field will be n times.
What is the formula for calculating flux?
If the electric field is uniform, the electric flux (ΦE) passing through a surface of vector area S is: ΦE = E⋅S = EScosθ, where E is the magnitude of the electric field (having units of V/m), S is the area of the surface, and θ is the angle between the electric field lines and the normal (perpendicular) to S.
What effect does a magnetic field have on a charge moving perpendicular to the field?
if a charge in a moving plane which is perpendicular to a uniform magnetic field, the particle will move in a circular trajectory. because the force is always perpendicular to the velocity, the magnitude of the velocity doesnt change, therefore the electrons move at constant speed.

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 is the flux through the plane perpendicular to the field?
Explanation: If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the vector, →A, then the flux through that surface is maximal. If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero.
What does it mean when magnetic flux is zero?
As shown in Figure 20.2, if the plane of the paper is parallel to the magnetic field, no field lines pass through the paper and the magnetic flux is zero.
What happens with the flux through a surface of fixed area when the surface is perpendicular to the field?
If the surface is perpendicular to the field (left panel), and the field vector is thus parallel to the vector, →A, then the flux through that surface is maximal. If the surface is parallel to the field (right panel), then no field lines cross that surface, and the flux through that surface is zero.
What is electric flux through the surface if the electric field is perpendicular to the surface?
electric flux that flows through the surface is zero.
What is the magnetic flux through a closed surface?
Magnetic flux through a closed surface is zero because the field lines entering the surface is equal to the field lines leaving the surface.
What is the magnetic field due to current in a solenoid?
Magnetic field due to a current in a Solenoid Magnetic field lines are parallel inside the solenoid, similar to a bar magnet, which shows that the magnetic field is the same at all points inside the solenoid. The magnetic field produced by a solenoid is similar to a bar magnet.
What is the magnetic field in a solenoid?
The formula for the magnetic field of a solenoid is given by, B = μoIN / L. Where, N = number of turns in the solenoid. I = current in the coil.
How do we find magnetic flux?
Magnetic flux can be measured with a magnetometer. Suppose a probe of the magnetometer is moved around an area of 0.6 m2 near a large sheet of magnetic material and indicates a constant reading of 5 mT. Then the magnetic flux through that area is calculated as ( 5 ×10-3 T) ⋅ (0.6 m2 ) = 0.0030 Wb.
When a charged particle moves through a magnetic field perpendicular to its direction then?
The path of motion of a charge particle approaching a magnetic field in a direction perpendicular to the direction of motion is circular. The direction of velocity changes at every point in circular motion but the magnitude remains constant. As a result, at each point, the tangential momentum will change.
When charge particle enter perpendicular to magnetic field the path followed by it is?
As the charged particle enters perpendicular to the magnetic field, the force will act perpendicular to the velocity. Thus the particle starts moving in the circular path. As force and displacement are perpendiculars the work done will be zero and kinetic energy will not change.

How do you calculate flux?
To find the total flux, we simply find the flux over the curved surface area by integrating, then find the flux through the two ends, and add them all up. This then defines all the ˆn vectors uniquely.
