To solve the problem it is necessary to have the concepts of the magnetic field in a toroid.
A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials.
By definition the magnetic field is given by the equation,
Where,
= Permeability constant
N = Number of loops
I = Current
r = Radius
According to the given data we have that the length is 120mm and the thickness of the copper wire is 4.82mm.
In this way the number of turns N would be
On the other hand to find the internal radius, we know that:
Therefore the total diameter of the soda would be
Applying the concept related to magnetic field you have to for the internal part:
The smallest magnetic field would be on the outside given by,
<em>Therefore the maximum magnetic field is 0.06T.</em>
Answer:
1410 Hz
Explanation:
Capacitance is reduced by 2, so the angular frequency will increase by a factor of .
