Figure 116, a shows a wire circuit placed in a uniform magnetic field. It is customary to say that a circuit in a magnetic field is penetrated by a certain magnetic flux F, or the flux of the magnetic induction vector.

Rice. 116. Dependence of the magnetic flux penetrating the contour area on the magnitude of the magnetic induction vector, the contour area and on the orientation of the contour plane relative to the magnetic induction lines

Experiments show that the magnetic flux through the circuit is proportional to the modulus of the induction vector of a homogeneous magnetic field and the area limited by this contour. In addition, the magnetic flux depends on how the plane of the circuit is located in relation to the lines of magnetic induction.

Let us assume that the induction of the magnetic field penetrating the area limited by the contour has become greater. This could happen, for example, as a result of an increase in the strength of the current creating this magnetic field, or when the circuit moves to another, stronger field.

Since the magnetic flux is proportional to the magnetic field induction, then when it increases n times (from the value of B 1 to the value of B 2 = nB 1, as shown in Fig. 116, a, b), the flux F penetrating the area will increase by the same amount S of this circuit.

With the same magnetic field with induction B 1, the magnetic flux penetrating large area S" (Fig. 116, c), will be the same number of times greater than the flow through the area S (see Fig. 116, a), how many times S" is greater than S.

If the plane of the contour is perpendicular to the lines of magnetic induction (see Fig. 116, a), then at a given induction B 1, the flux F penetrating the area S limited by this contour is maximum.

When the circuit rotates around the OO axis, the magnetic flux passing through it decreases (according to the cosine law) and becomes equal to zero when the plane of the circuit is parallel to the lines of magnetic induction (Fig. 116, d). In this case, the lines of magnetic induction seem to slide along the plane frame without penetrating it.

Thus, the magnetic flux penetrating the area of ​​the circuit changes when the magnitude of the magnetic induction vector d, the area of ​​the circuit S changes, and when the circuit rotates, i.e., when its orientation changes relative to the lines of magnetic field induction.

If the circuit rotates so that, at any position, the lines of magnetic induction lie in the plane of the circuit, without crossing the area limited by it (Fig. 117), then the flux does not change: at any moment of time it is equal to zero.

Questions.

1. What determines the magnetic flux that penetrates the area of ​​a flat circuit placed in a uniform magnetic field?

From the magnetic induction vector B, the area of ​​the circuit S, and its orientation.

2. How does the magnetic flux change when the magnetic induction increases n times, if neither the area nor the orientation of the circuit changes?

1. A wire coil K with a steel core is connected to a DC source circuit in series with a rheostat R and a switch K (Fig. 125). The electric current flowing through the turns of the coil K1 creates a magnetic field in the space around it. In the field of coil K 1 there is the same coil K 2. How can you change the magnetic flux passing through the K2 coil? Consider everything possible options.

The magnetic flux passing through coil K 2 can be changed: 1) by changing the current strength I with a rheostat; 2) by closing and opening the key; 3) changing the orientation of coil K 2.

1. Magnetic induction: What is the quantity, its designation 2. What are called magnetic induction lines? 3. In what case is the magnetic field called homogeneous, and in what case is it called inhomogeneous? 4. How does the force acting at a given point in the magnetic field on a magnetic needle or a moving charge depend on the magnetic induction at this point?

A circuit in a magnetic field is penetrated by a certain magnetic flux Ф or the flux of the magnetic induction vector. This means that the magnetic flux penetrating the circuit is proportional to the modulus of the induction vector of a uniform magnetic field and the area limited by this circuit depends on how the plane of the circuit is located in relation to the lines of magnetic induction.

The magnetic flux penetrating a large area will be the same number of times greater than the flux penetrating a smaller area. When the circuit rotates around the OO axis, the flux passing through it decreases and becomes equal to zero when the plane of the circuit is parallel to the lines of magnetic induction. The lines of magnetic induction seem to slide along the plane of the frame without penetrating it.

CONCLUSION: the magnetic flux penetrating the circuit area changes when the magnitude of the magnetic induction vector changes, the circuit area and when the circuit rotates, i.e. when its orientation changes relative to the magnetic field induction lines. What happens to the magnetic flux (how does it change) and what is it equal to in the figure? F = SB

A wire coil K1 with a steel core is connected to a DC source circuit in series with a rheostat R and a switch K. The electric current flowing through the turns of the coil K1 creates a magnetic field in the space around it. In the field of coil K1 there is the same coil K2. How can you change the magnetic flux passing through the K2 coil? Consider all possible options.
