Question

У прямолінійному провіднику завдовжки 60 см тече струм силою 1.2 А. Провідник розташований в однорідному магнітному полі індукцією 1.5 Тл. Визначте найбільше та найменше значення сили Ампера, яка може діяти на провідник.

Answer 1

F=I*B*L*sina
1) a=90  Fmax=I*B*L=1,2*1,5*0,6=1,08 H
2) a=0   Fmin=1,2&1,5*0,6*0=0 H

Answer 2

Calculation of the Maximum and Minimum Values of Ampere's Force

To determine the maximum and minimum values of Ampere's force acting on the conductor, we need to use the formula for calculating Ampere's force:

F = BIL

Where: - F is the force acting on the conductor (in Newtons), - B is the magnetic field strength (in Tesla), - I is the current flowing through the conductor (in Amperes), - L is the length of the conductor (in meters).

Given the following information: - Length of the conductor (L) = 60 cm = 0.6 m - Current flowing through the conductor (I) = 1.2 A - Magnetic field strength (B) = 1.5 T

We can substitute these values into the formula to calculate the maximum and minimum values of Ampere's force.

Maximum Value: To find the maximum value of Ampere's force, we assume that the current is flowing perpendicular to the magnetic field. In this case, the force will be at its maximum.

F_max = BIL

Substituting the given values: F_max = (1.5 T) * (1.2 A) * (0.6 m)

Calculating the result: F_max = 1.08 N

Therefore, the maximum value of Ampere's force that can act on the conductor is 1.08 Newtons.

Minimum Value: To find the minimum value of Ampere's force, we assume that the current is flowing parallel to the magnetic field. In this case, the force will be at its minimum.

F_min = 0

When the current flows parallel to the magnetic field, there is no force acting on the conductor.

Therefore, the minimum value of Ampere's force that can act on the conductor is 0 Newtons.

In summary, the maximum value of Ampere's force that can act on the conductor is 1.08 Newtons, while the minimum value is 0 Newtons.
