This nugget describes the nucleus of an atom. It talks about the various aspects of a nucleus like atomic number, atomic mass unit, isotopes and isobars, with examples.

AP Physics C: Electricity and Magnetism review inductance, inductors, and self-inductance. The equation for the inductance of an ideal solenoid is derived. The differences between resistance, resistors, resistivity, inductance,...

It explains the principle of an electric motor, its construction and working.

How do you take copper wire, a battery and magnets and make electric train? With science! This super simple DIY physics demo uses electromagnetic induction to propel a train made of magnets and batteries.

AP Physics C: Electricity and Magnetism review of magnetic fields including: the basics of magnetic dipoles, ferromagnetic and paramagnetic materials, the Earth’s B field, magnetic permeability, the magnetic force on a moving charge, the...

Antarctica's Weddell seals have biological adaptations that allow them to dive deep—as much as of hundreds of meters—while hunting, but also an uncanny ability to find the breathing holes they need in the surface of the ice that...

How a superconductor works. Everything from the physics and some of the history as well. Superconductors were discovered in 1911 by Heike Kamerlingh Onnes. It was discovered because it was made possible to liquefy helium which produced...

An induction cooker is a modern and energy-efficient cookware that uses magnetic induction instead of fire to cook food. It operates by creating a magnetic field that heats up the pot through currents, resulting in faster and more...

Paramagnetism and Molar Susceptibility

When a current passes through a wire it produces a magnetic field. If you put this magnetic field in another magnetic field, it puts a force on the wire. This is known as the motor effect. To determine the direction of the force you use...

This video explains how to calculate the magnitude of the force acting on a conducting wire when it is placed in a magnetic field. The video starts by explaining the motor effect and how a current carrying conductor experiences a force...

Watch a soda can rip itself apart in a fiery explosion at 11,000fps with a Phantom high speed camera. Running a current through a coil, produces an electromagnet. Turn up the voltage in this experiment, and make that current strong...

This nugget explains the construction and working of an important application of electromagnetic induction and AC generator.

On why I was very wrong. In my previous video, I said that spin isnt very linked to angular momentum at all- but in fact, theres a key property of angular momentum that spin has, suggesting they are linked after all. Book recommendation:...

Orbitals! Oh no. They're so weird. Don't worry, nobody understands these in first-year chemistry. You just pretend to, and then in second-year you learn them a little better, the following year a little better, and once you have a PhD...

This is a lecture video explaining how loudspeakers work by utilizing the motor effect, which is when a current-carrying conductor experiences a force when placed in a magnetic field. The video demonstrates this effect on a conductor...

What is known about sunspots? How does the sun and the magnetic field affect each other? The Powerhouse Sun, Part 2

This is a lecture on electromagnetic devices, exploring the real-world applications of electromagnets. The video describes how an electromagnet works, with a solenoid and iron core generating a magnetic field when a current is flowing...

When we cut the electricity to an inductor, we get a sudden intense spark across the switch. This is known as inductive kickback or a back EMF and is produced because of Faraday’s Law of Induction. Not mean to be tried at home! The...

This video explains the fundamental concepts of magnetism, including permanent magnets, magnetic fields, induced magnetism, and the interactions between magnets. It provides a clear understanding of how magnets operate, the difference...

Current & Magnetic Fields | Magnetism | Physics | FuseSchool Electromagnets are incredibly useful. They can do all the things a normal magnet can do, but can also be switched on and off. Electromagnets have many uses, from moving cars in...

The video explains how an electric current flowing through a conducting wire produces a magnetic field around the wire. The video explores some of the uses of electromagnetism, including electromagnetic lifts used to separate iron and...

This video is a lecture on solenoids and the magnetic field that forms around them. The lecturer explains the concept of magnetic fields and how they can form around conducting wires. They demonstrate how the direction of the current...
