Let's discuss this question.
00:02
So here the problem takes for us through the steps needed to calculate the magnetic field of toroidal solenoid from ampera's law.
00:10
The toroidal solenoid is a solenoid wrapped on the circular tube and the appropriate emperian path is drawn as a dash line in the figure to the right and the radius of the path is r.
00:23
So we need to assume the circles with radii a, b and r are all in the same plane and the solenoid is.
00:30
Wound with n turns.
00:32
So here firstly we need to say if current i flows through the wire what will be i, e and c.
00:38
And secondly we need to evaluate phi b dash multiplied by dl dash that is dl vector and thirdly we need to calculate the magnetic field.
00:48
So here we can say imperian path will be taken as n and therefore we can say total current and closed will be equal to n and here we have arrow so now here we need to find b that is using ampiers law here we can say phi that is equal phi m will be multiplied by b vector multiplied by d l vector that is equal to mu not i enclosed so here we can say phi m multiplied by b vector multiplied by dl vector will be equal to mu not multiplied by n.
01:53
So here therefore, phi m b vector multiplied by dl vector is equal to mu not n.
02:02
So this is the value...
