5.9 Ley de Ampere - Campo creado por un solenoide

New Section

In this section, the speaker introduces the topic of calculating the magnetic field created by a solenoid using Ampere's law. The concept of a solenoid as a coil or multiple turns of wire is explained.

Introduction to Solenoid and Ampere's Law

• The speaker discusses the representation of current in a solenoid, highlighting the direction of current flow at different points within the coil.

• Choosing an appropriate Amperian loop for symmetry is emphasized, with the selection of a rectangular or square loop due to the infinite nature of the solenoid.

• Explaining how to set up line integrals around the chosen contour, focusing on breaking down the integral into components related to magnetic fields along different segments.

• Analyzing specific segments of line integrals and their contributions to overall calculations, particularly noting instances where certain integrals become zero based on magnetic field characteristics.

Magnetic Field Calculation within Solenoid

• Emphasizing parallel alignment between vector dl and magnetic field components within the solenoid, leading to simplification in calculations due to constant magnetic field properties.
