In what condition will the magnetic flux through a surface of a fixed area be at its maximum value?
The magnetic flux through the plane of the coil has its maximum value when this plane is perpendicular to the magnetic field lines between the poles.
Can the magnetic flux be zero when the magnetic field is not zero?
Answer. Explanation:Inside any closed surface, there will always be magnetic dipoles. Since each pole of the dipole will provide equal and opposite flux through the surface, yeah the magnetic flux through a closed surface will be always zero. There, the net flux will in general be non-zero.
Why is the magnetic flux through a closed surface always zero?
Because magnetic field lines are continuous loops, all closed surfaces have as many magnetic field lines going in as coming out. Hence, the net magnetic flux through a closed surface is zero.
Under what condition the magnetic flux linked with a circuit is zero?
When plane of coil is along the direction of field, the magnetic flux linkedwith a coil is zero.
What is maximum magnetic flux?
a) The magnetic flux is maximum when the plane of the coil is perpendicular to the magnetic field i.e, θ = 0° Therefore, Φ = NBA cos θ = NBA cos 0° =NBA (maximum). b) The magnetic flux is minimum when the plane of the coil is parallel to the magnetic field i.e θ = 90°
What is the flux through the coil when the current is zero?
Due to which an emf is induced in the other coil and as the loop is closed, current starts flowing which is being driven by the induced force. Hence, if a current is zero means the flux linkage and the flux is zero.
What is the flux through the coil when the current is zero What is the flux when the current is maximum?
When current is zero, magnetic flux through the coil is maximum. On the other hand, when current is maximum, the coil is horizontal. The flux linked with the coil is minimum. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
What is the emf induced when current is reduced to zero?
= 40 * 10-7 * 1.5 x 22000 * 3.464 x 10-4 = 1.44 * 10-5 Wb Finally the flux becomes zero because the current reduces to zero. Thus, e=140 / 1.44 x 10-5 At 25×10-5=5.76 x 10-4 v The total emf = Nxe = 130 * 5.76 x 10-4 = 75 mV Try Yourself 4.
What is value of flux?
Flux as flow rate per unit area. In transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the rate of flow of a property per unit area, which has the dimensions [quantity]·[time]−1·[area]−1. The area is of the surface the property is flowing “through” or “across”.
What is flux in diffusion?
Fick’s First Law of Diffusion J is the flux and is defined by the number or particles that are moving past a given region divided by the area of that region multiplied by the time interval. The units of J are mol m-2 s-1.
What affects diffusion flux?
Diffusion coefficients vary with temperature and pressure following the Arrhenius relationship. (5) Eq. (4) expresses that the flux of ions from reactant to product grains depends not only on chemical activity differences and on diffusion coefficients, but also on distances of separation of the two.
