Question

Чему равен магнитный поток через рамку площадью 50 см^2, находящуюся в магнитном поле с индукцией 1 мТл, если угол между плоскостью рамки и вектором магнитной индукции составляет 30 градусов?

Answer 1

дано                        

s= 50СМ^2= 0,005 м^2

B= 1мТл= 10^-3 Тл

β= 30

НАЙТИ  Ф

.......................................................

Ф= B S cosα

α= 90- β= 90-30= 60

Ф= 10^-3 * 0,005 * cos60= 0,0025 * 10^-3= 2,5*10^-6 Вб

Answer 2

Calculation of Magnetic Flux

To calculate the magnetic flux through a loop, we can use the formula:

Φ = B * A * cos(θ)

Where: - Φ is the magnetic flux through the loop, - B is the magnetic field strength (also known as magnetic induction or magnetic flux density), - A is the area of the loop, and - θ is the angle between the plane of the loop and the direction of the magnetic field.

In this case, we are given the following values: - The area of the loop (ramka) is 50 cm^2. - The magnetic field strength (induktsiya) is 1 mT (millitesla). - The angle between the plane of the loop and the direction of the magnetic field is 30 degrees.

Let's substitute these values into the formula to calculate the magnetic flux.

Φ = (1 mT) * (50 cm^2) * cos(30 degrees)

To perform the calculation, we need to convert the units to the appropriate SI units: - 1 mT = 0.001 T (tesla) - 50 cm^2 = 0.005 m^2

Φ = (0.001 T) * (0.005 m^2) * cos(30 degrees)

Now, let's calculate the result.
