Can we proceed with Biot Savart's law?
If so what is the final expression?
An elliptical coil is a type of electromagnetic coil that has a shape resembling an ellipse. It is typically used to generate a magnetic field in a specific direction.
The magnetic field of an elliptical coil can be calculated using the formula B = μnI(1 + k^2)/√(a^2 + b^2), where B is the magnetic field, μ is the permeability of the medium, n is the number of turns in the coil, I is the current, k is the ellipticity factor (ratio of major to minor axis), and a and b are the major and minor radii of the coil.
The strength of the magnetic field in an elliptical coil is affected by the number of turns in the coil, the current flowing through the coil, and the shape of the coil (specifically, the ellipticity factor).
An elliptical coil allows for more control over the direction and shape of the magnetic field compared to a circular coil. This can be useful in certain applications, such as in magnetic sensors or in medical devices.
Yes, an elliptical coil can be used for both generating and detecting magnetic fields. By passing a current through the coil, it can generate a magnetic field. And by measuring the changes in the magnetic field, it can also be used as a sensor to detect changes in the environment.
