I have a problem to share with you guys.

How can I calculate the thickness of my solenoid if I have these values;

Solenoid long : 20cm

magnetic field, B : 5Tesla

Current, I : 20A

Thanks a lot for your help. I appreciate that

5T, yeah I know , it's a lot. is it possible?

B=μnI this is only valid if the proportion between the thickness and the longeur is huge.

Since stronger magnets have been built, it's possible.

Within any construction constraints you might have, no idea.

Good luck with that.

For example,formula for [tex]B[/tex] in center of solenoid is:

[tex]B=\frac{\mu_0NI}{\sqrt{4R^2+l^2}}[/tex]

For example,formula for [tex]B[/tex] in center of solenoid is:

[tex]B=\frac{\mu_0NI}{\sqrt{4R^2+l^2}}[/tex]

It's in the air at the center of the solenoid.

p/s:

I found a formula

[tex]B=\frac{\mu_0NI}{\sqrt{R^2+l^2}}[/tex]

So now I confuse, it's 4R^2 or R^2?

You are right,it is error in my book.But still you don`t have [tex]N[/tex] given.

the thickness of the solenoid depends on the value of N.

[tex]N[/tex] is number of loops.
