We compare the properties of three iron mixtures: iron and water, iron and oil and a ferrofluid - a mixture of compounds containing iron and oil. First, we look at how iron filings behave when mixed with water and then oil. We then hold...

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...

We examine the different properties of iron and sulfur when they are mixed and when they are chemically combined. When iron and sulfur are mixed they retain their individual properties. When they react chemically to form iron sulfide...

What are the properties of magnets, and why are they useful to us? Physics - Electricity And Circuits - Learning Points. A permanent magnet is a piece of metal that possesses a magnetic field. The magnetic field is strongest at the...

In this episode, Mr. P takes us deeper into Faraday's law, exploring the crucial element of direction by introducing Lenz's law. Lenz's law states that the induced current in a circuit, due to a change in magnetic flux, is directed to...

Unravel the intricacies of ideal solenoids with us! We break down the equations for induced emf, exploring Faraday's Law and the inductor formula. Dive deep into integrals, variables, and solenoid length, demystifying the math behind...

In this next episode, Mr. P guides us through the culmination of electromagnetic knowledge – Maxwell's equations. After a quick recap of Gauss's law and its magnetic counterpart, the class dives into Faraday's law of induction, unveiling...

In this episode, Mr. P delves into Gauss's law for magnetism, unraveling the mysteries of magnetic flux through closed surfaces. Exploring the hypothetical existence of magnetic monopoles, the class speculates on the implications of...
