Effects of Magnetic Fields

The video tutorial explains the concept of magnetic fields, which are invisible areas around magnets where magnetic forces occur. It describes how these fields can be visualized using iron filings, which align along the magnetic field lines. The tutorial also covers how magnetic fields interact, showing attraction between opposite poles and repulsion between like poles, using both illustrations and real-life examples with iron filings.

What happens when two magnets with the same poles are placed together?

How can you visualize a magnetic field if it is invisible?
