Question

Какая сила действует на проводник длиной 20 см в однородном магнитном поле с индукцией 2 Тл, если сила тока в проводнике 40 А, а угол между направлением тока и направлением поля 45 градусов?

Answer 1

Дано:
L=20*10^(-2)м
I=40 А
В=2 Тл
а=45°
--------------
F-?
Решение:

F=BIL*sin45
F=2*40*20*10^(-2)*√2/2=8√2≈11.3 H

Ответ: 11.3 Н

Answer 2

Calculation of the Force on a Conductor in a Magnetic Field

To calculate the force acting on a conductor in a magnetic field, we can use the formula:

F = BILsinθ

Where: - F is the force on the conductor, - B is the magnetic field induction, - I is the current flowing through the conductor, - L is the length of the conductor, and - θ is the angle between the direction of the current and the direction of the magnetic field.

In this case, we have the following values: - Length of the conductor (L): 20 cm (0.2 m) - Magnetic field induction (B): 2 T - Current flowing through the conductor (I): 40 A - Angle between the direction of the current and the direction of the magnetic field (θ): 45 degrees

Substituting these values into the formula, we can calculate the force:

F = (2 T)(40 A)(0.2 m)sin(45 degrees)

Let's calculate the force using these values.
