Compare the magnetic field of magnets in attraction vs repulsion when placed in front of an old Cathode Ray Tube (CRT) TV. Note how much more condensed the field is for the magnets in repulsion! ๐Ÿ˜ฎ
Pretty interesting how the magnets in attraction form just one magnetic domain Bloch wall / node, while the magnets in repulsion form two.

And even more interestingly, is that when the magnets in repulsion are clamped together with a steel clamp, the magnetic domain loops around the steel! ๐Ÿ˜ฎ

Why 9/11 disinfo "debunker" trolls gotta type such long nonsense that no one got time or the will power to read through ๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก๐Ÿคก

Exercise 4: Proof of Formula 5: Derivative of Cross Product of Vector Functions by Components - YouTube - Summary - Notes - Playlist - Vector Functions playlist

In this video I prove Formula 5 of the differentiation rules for vector functions, and this time derive the derivative of the cross product of two vector functions. I solve this by taking the derivative of the components of the cross product directly and then separating it into two vectors.
