Question

A circular loop of radius 0.0400 m is

oriented 75.0 degrees to a magnetic

field. If the magnetic flux through the

loop is 9.59 x 10^-7 Wb, what is the

strength of the field?
___x10^__-T

Answer 1

any ideas?

Answer 2

of wat

Answer 3

do you know how to calculate magnetic flux

Answer 4

no

Answer 5

it's essentially just the strength of magnetic field multiplied by the area it's acting upon

Answer 6

since your circular loop is tilted at an \(75^o\) to the direction of the magnetic field you can't just multiply the area of the circle with the field strength to get the magnetic flux

Answer 7

can u do it

Answer 8

you're gonna do the calculations

Answer 9

but can u plug it in

Answer 10

you'll have to take the component of the area which is perpendicular to the direction of the field and multiply it with field strength to get magnetic flux

Answer 11

just do it

Answer 13

\(Area \times \sin(angle~with~the~field) \times strength~of~field = magnetic~flux\)

Answer 14

plug in the number s thats all

Answer 15

why don;t you do it? isn't it your homework?

Answer 16

ya but just help me out real quick

Answer 17

are you not able to plug in the values

Answer 18

i did plug it the values but threa nswer still seems to be wrong

Answer 19

What is the area of a circular loop of radius 0.04 m?

Multiply that by sin 75

And then magnetic flux divided by that number that you got previously will give you the strength of the field

Also if you show us your work, it'll be easier for us to see where you're making the mistake and help you better :)

Answer 20

i dont the the magnetic flux and dont know the answer

Answer 21

How do you find the area of a circle? Do you know the formula?


They gave the magnetic flux in the question itself. Reread the question.

Answer 22

If you work with us, we can solve this question much much faster. But you have to tell us what you know, where you're stuck, and how far you've gotten

Answer 23

just tell me the step by step for this question and i can solve the rest or you just acn send me the link of the calculator to use

Answer 24

I just broke it down step by step

I'm not sure what's making this question difficult for you

You have a formula
You are given all these values and you plug them in
You have one variable left which you solve for

Do you understand that?

Now, do you know the formula for finding the area of a circle? Can you find the area if r = 0.04 m

Multiply that by sin(75)

Now whatever number you get, let's call that 'x'
Idk this number rn, you have to find it

Now you do magnetic flux/x
Magnetic flux is given in the question as 9.59*10^-7

And then you're done

Answer 25

Wait apparently the equation is

magnetic flux = magnetic field * area * cos \(\theta\)

So you should be doing cos(75)
