The video tutorial covers the concept of magnetic flux, explaining it as the amount of magnetism an object experiences. It introduces the formula for calculating magnetic flux, involving magnetic field strength, area, and angle, with units in Weber. The tutorial provides practical examples using square and circle shapes, demonstrating calculations and considering angles between the magnetic field and the normal. The session concludes with a final example and a summary of key points.
