Question

Яка сила діє з боку однорідного магнітного поля з індукцією 50 мТл на прямолінійний провідник завдовжки 60 см, що перебуває в полі? Провідник утворює прямий кут із напрямком ліній магнітного поля, сила струму в провіднику дорівнює 8 А

Answer 1

Дано:
B = 50 мТл = 0,050 Тл
L = 60 см  = 0,60 м
I = 8 A
α = 90°
__________
F - ?

На проводник с током в магнитном поле действует сила Ампера:
F = B*I*L*sin α
F = 0,050*8*0,60*1 = 0,24 Н

Answer 2

Calculation of the Force on a Straight Conductor in a Magnetic Field

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

F = BILsinθ

Where: - F is the force acting on the conductor, - B is the magnetic field strength, - 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 magnetic field and the conductor.

In this case, we have the following values: - B = 50 mT (0.05 T)- I = 8 A - L = 60 cm (0.6 m) - θ = 90° (since the conductor forms a right angle with the direction of the magnetic field)

Plugging these values into the formula, we get:

F = (0.05 T) * (8 A) * (0.6 m) * sin(90°)

Simplifying the equation, we find:

F = 0.24 N

Therefore, the force acting on the straight conductor in the magnetic field with an induction of 50 mT is 0.24 N.

Please note that the angle between the conductor and the magnetic field is crucial in determining the force. If the angle is not 90°, the force will be different.
