Lane Kugler has forgiven his son-in-law for stabbing to death his only daughter and two grandsons. But he has nothing but ...

In this captivating experiment, explore the fascinating world of electric motors and their magnetic rotors in motion.

A novel metamaterial emits significantly more heat than it absorbs under a magnetic field, breaking Kirchhoff’s law.

New results published in the journal Physical Review Letters detail how a specially designed metamaterial was able to tip the ...

It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The Biot-Savart law defines the magnetic field vector around an electrical segment. Its calculation involves a cross product, but certain physical properties of this operation are not fully ...

Magnetic Field around a current carrying wire Oersted’s law states that an electric current induces a magnetic field. It was observed that current-carrying wires created a circular magnetic field ...

Magnetic fields are everywhere in the universe. Of course, there's Earth's magnetic field, which deflects dangerous cosmic radiation, wiggles our compasses, and guides flocks of migrating birds.

Figure 2. Lenz’s law and conservation of energy. One can now see that, due to the negative of Lenz’s law (the induced magnetic field opposes the change of the original magnetic flux) that the original ...
