Question

На проводник длиной 80 см со стороны магнитного поля действует сила 0,2H Определите силу тока и направление если индукция 0,04 Тл.

Answer 1

L=80 см=0,8 м      сила Ампера: F=BIL  ⇒   I=F/BL;
F=0,2 H                                                          I=0,2/0,04*0,8=0,0625 A
B=0,04 Тл                                                      Ответ: I=0,0625 A
I-?                         направление тока определяют провилом буравчика.

Answer 2

Calculation of Current and Direction

To determine the current and direction in a conductor of length 80 cm under the influence of a magnetic field with an induction of 0.04 T and a force of 0.2 H, we can use the formula:

F = B * I * l * sin(theta)

Where: - F is the force on the conductor (0.2 H) - B is the magnetic field induction (0.04 T) - I is the current in the conductor (to be determined) - l is the length of the conductor (80 cm or 0.8 m) - theta is the angle between the direction of the magnetic field and the direction of the current (90 degrees for maximum force)

Rearranging the formula, we can solve for the current (I):

I = F / (B * l * sin(theta))

Substituting the given values into the formula:

I = 0.2 H / (0.04 T * 0.8 m * sin(90 degrees))

Simplifying the equation:

I = 0.2 H / (0.04 T * 0.8 m * 1)

I = 0.2 H / (0.032 T*m)

I ≈ 6.25 A

Therefore, the current in the conductor is approximately 6.25 A.

Since the force is acting on the conductor in a specific direction, we can determine the direction of the current using the right-hand rule. The right-hand rule states that if you point your thumb in the direction of the force, and your fingers in the direction of the magnetic field, then the direction in which your palm faces will be the direction of the current.

Unfortunately, the search results did not provide specific information about the direction of the magnetic field or the force. Therefore, without this information, we cannot determine the exact direction of the current.
