Earth’s magnetic field protects us from deadly space radiation. What if it were drastically weakened, as a precursor to flipping upside down? I mean, it has before … many, many times..

Spaceship Earth has a literal deflector...

The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

Quantum field theory is notoriously complicated, built from mind-bendingly abstract mathematics. But are the underlying rules of reality really so far from human intuition? Or are physicists just showing off? For better or worse, the...

In this video Paul Andersen explains how the magnetic permeability is the ability of a material to form internal magnetic fields. The magnetic permeability of free space is a constant and is much lower than the magnetic permeability of...

The magnetic dipole moment is the torque experienced by a material placed in a magnetic field. The magnetic dipole is an intrinsic property at the magnet, domain, atom, and electron level. A magnetic dipole creates magnetic fields that...

In this video Paul Andersen explains how magnetic domains act as tiny magnets within ferromagnetic material.

In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

This colorful video program takes a look at the many different types of forces. Magnetic, electric, and gravitational forces are all explored. Special emphasis highlights how these forces impact our everyday lives. This video correlates...

Pupil outcome: I can describe how to make a magnet using an electric current. Key learning points: - When there is an electric current in a wire, there is a magnetic field around the wire. - When there is an electric current in a coil of...

We use two magnets and a set of scales to examine magnetic field and strength. One magnet is attached to the scales and a second is lowered towards it. When opposite poles are facing each other, the weight on the scales decreases as the...

“Effects of Magnetic Fields” reviews the concept of a magnetic field and demonstrates how a magnetic field can be shown using simple iron filings and bar magnets.

This problem is about using the Right Hand Rule to determine the Net Magnetic Force on a current carrying loop near a Bar Magnet.

Upon viewing the Magnets and Electromagnets video series, students will be able to do the following: Define a magnet as a material that attracts iron and materials containing iron. Explain that magnets have a north pole and a south pole...

This video explores how the direction of an induced potential within a conducting wire is affected by the direction in which the magnetic field that produces the potential moves. It covers the concept of electromagnetic induction and how...

This video explores the force of magnetism and how it affects our everyday lives. The atomic nature of magnetism is illustrated, and then applied in principle to common magnets. The video highlights how magnetic fields are created, and...

With NASA planning to send astronauts to the Moon by 2024, Steve Mackwell chats about the Moon’s exciting unexplored areas.

Weve talked about the quantum state plenty- but what happens to it over time? Thats exactly the question the Schrodinger equation solves. This video we talk about Linearity. In the next video we discuss the equation itself and its...

This video discusses how alternators use the generator effect to produce an alternating current. The video explains how this effect can be utilized to generate both alternating and direct currents, and how the direction of the potential...

Research assignment: Teach me about spin. Below there are suggested questions, recommended sources and my social media accounts: QUESTIONS: Questions that require less research: 1. This is our first real example of quantization, the...

This nugget explains the formation and behaviour of magnetic field lines. It also explains mathematical parameters of a bar magnet and a solenoid.
