Calculating Magnetic Flux in a Bent Square Loop with a Uniform Magnetic Field

In summary, magnetic flux is a measure of the total magnetic field passing through a given area and is represented by the symbol Φ. It is calculated by multiplying the strength of the magnetic field (B) by the perpendicular area (A). The factors that affect magnetic flux include the strength of the magnetic field, the size of the area it passes through, and the angle between the field and the area. The unit of magnetic flux is the Weber (Wb), which is equivalent to 1 Tesla (T) multiplied by 1 square meter (m²). Magnetic flux is used in various practical applications such as generators, motors, transformers, and magnetic storage devices, as well as to measure the strength of a magnetic field and study the behavior

Magnetic flux...PLEASE HELP!

Homework Statement


A 13.5 cm × 13.5 cm square bent at a angle 90°. A uniform 0.463 T magnetic field points downward at θ=33° angle. What is the magnetic flux through the loop? (a=6.75 cm, b=13.5 cm, c=6.75 cm.)

Homework Equations





The Attempt at a Solution


MF = AB cos theta
Would it just be (.135 * .135) * 0.463 cos 33
I am not sure which area and angle to use?

To calculate the magnetic flux through the loop, you can use the formula MF = AB cos θ, where A is the area of the loop and θ is the angle between the magnetic field and the normal to the loop. In this case, A = 13.5 cm * 6.75 cm = 91.125 cm^2 and θ = 33°. Plugging these values into the formula, we get MF = (91.125 cm^2) * (0.463 T) * cos 33° = 38.98 mT*cm^2. Therefore, the magnetic flux through the loop is 38.98 mT*cm^2.
 

1. What is magnetic flux?

Magnetic flux is a measure of the total magnetic field passing through a given area. It is represented by the symbol Φ and is measured in units of Webers (Wb).

2. How is magnetic flux calculated?

Magnetic flux is calculated by multiplying the strength of the magnetic field (B) by the perpendicular area (A) that the field passes through. The formula is Φ = B x A.

3. What factors affect magnetic flux?

The strength of the magnetic field, the size of the area it passes through, and the angle between the field and the area all affect the value of magnetic flux.

4. What is the unit of magnetic flux?

The unit of magnetic flux is the Weber (Wb), which is equivalent to 1 Tesla (T) multiplied by 1 square meter (m²).

5. How is magnetic flux used in practical applications?

Magnetic flux is used in various applications such as generators, motors, transformers, and magnetic storage devices. It is also used to measure the strength of a magnetic field and to study the behavior of magnetic materials.
