A 3D small deformation theory is developed to examine the motion of a magnetic droplet in a uniform rotating magnetic field. The equations describing the droplet's shape evolution are derived using two different approaches - a phenomenological equation for the tensor describing the anisotropy of the droplet, and the hydrodynamic solution using perturbation …

Tapping into Earth's rotation. Although the Earth's magnetic field is not aligned exactly with the planet's rotation axis, there is a component of the field that is symmetric about this axis. A proposed device interacting with this component would extract energy from the Earth's rotation to produce electric power.

A rotary encoder is a position sensor used to determine the angular position of a rotating shaft. It can be used with an Arduino through modules to achieve such functionality. With two main types of rotary encoder available (Absolute encoder and Incremental encoder) that adopt different functional technologies, one would beg to wonder how does all of them work?

This was an exciting discoverery that not only verified the theory of Continental Drift, but demonstrated that earth's magnetism isn't constant over millions of years. The magnetic field of earth actually changes its polarity over time. They are called Polarity Reversals, but should not be confused with the rotation axis of earth actually changing.
