Question

Магнитное поле действует на проводник длиной 2м с силой 20Н. Определите силу тока в проводнике, если вектор магнитной индукции равен 25Тл.

Answer 1

Calculation of Current in the Conductor

To determine the current in the conductor, we can use the formula that relates the force acting on a conductor in a magnetic field to the current flowing through it. The formula is as follows:

F = BIL

Where: - F is the force acting on the conductor (given as 20 N) - B is the magnetic field strength (given as 25 T) - I is the current flowing through the conductor (to be determined) - L is the length of the conductor (given as 2 m)

We can rearrange the formula to solve for the current I:

I = F / (BL)

Substituting the given values, we have:

I = 20 N / (25 T * 2 m)

Calculating this expression, we find:

I ≈ 0.4 A

Therefore, the current flowing through the conductor is approximately 0.4 Amperes.
