Question

Прямолинейный проводник с активной. Прямолинейный проводник с активной длинной 0,5 м расположен под углом 30° к линиям индукции однородного магнитного поля. С какой силой действует магнитное поле с индукцией 4 Тл на этот проводник, если по нему проходит ток 20 А?

Answer 1

На проводник действует сила Ампера: Fa=BIL·sinα = 4·20·0,5·0,5=20 H

Answer 2

Calculation of the Magnetic Force on a Straight Conductor

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

F = BILsinθ

Where: - F is the magnetic force (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) - θ is the angle between the conductor and the magnetic field lines (in degrees)

In this case, we have a straight conductor with a length of 0.5 meters and an angle of 30° with respect to the magnetic field lines. The magnetic field has an induction of 4 Tesla, and a current of 20 Amperes is flowing through the conductor.

Using the given values, we can calculate the magnetic force as follows:

F = (4 T)(20 A)(0.5 m)sin(30°)

Calculating the value:

F = (4)(20)(0.5)(0.5) = 20 N

Therefore, the magnetic field with an induction of 4 Tesla exerts a force of 20 Newtons on the conductor with a current of 20 Amperes and a length of 0.5 meters, when it is placed at an angle of 30° to the magnetic field lines.

Please note that the calculation assumes the conductor is in a uniform magnetic field and that the current is flowing perpendicular to the magnetic field lines.
