Question

Чему равна магнитная индукция однородного магнитного поля если на проводник расположенный перпендикулярно вектору индукции, с током 10 А и длиной 40см действует сила 8 Н?

Answer 1

$F_A=\mathcal {BI}lsin\alpha \Rightarrow \mathcal B= \frac{F_A}{\mathcal Ilsin\alpha}\\ \mathcal B= \frac{8}{10*0,4*1}=2T\Lambda$

Answer 2

Calculation of Magnetic Induction

To calculate the magnetic induction of a uniform magnetic field, we can use the formula:

B = (F * L) / (I * sinθ)

Where: - B is the magnetic induction (in teslas, T) - F is the force acting on the conductor (in newtons, N) - L is the length of the conductor (in meters, m) - I is the current flowing through the conductor (in amperes, A) - θ is the angle between the direction of the magnetic field and the direction of the current

In this case, we are given the following information: - The force acting on the conductor is 8 N. - The current flowing through the conductor is 10 A. - The length of the conductor is 40 cm (or 0.4 m).

However, we are not given the value of the angle θ. Without this information, we cannot calculate the exact value of the magnetic induction.
