Electric Circuits Part 5 – Effects of the Electric Current , the Fuse

Hi and welcome to part 5 of the introduction to Electric Circuits! In this part: Main effects of the electric current. The three main effects of an electric current are: magnetic, chemical and heating effect. Some of the most common practical applications of the effects of an electric current include: relays, bells, motors, generators and […]

Exotic Elements vs. Magnet | Thor’s Metal? | Part 6/6

Hi! I have finally found and been able to afford five new elements besides the 69 I have already shown in previous episodes. I will show you the new, beautiful and beasty samples and their reaction near a magnet. All five are ‘a little’ on the hazardous side so let’s change my usual hazard roulette […]

How Special Relativity Makes Magnets Work

Only a few elements can be permanent magnets – iron is one. Copper is not. But if you pass an electric current through any metal it becomes a magnet – an electromagnet. But how does this work? Well strangely enough, it’s a consequence of special relativity. Special relativity is the fact that in our universe, […]

Review of all Electricity and Magnetism Dimensions – AP Physics C

Bo: Hey guys. Billy: Hey Bo. Bobby: Hi Bo. ♫ (lyrics) Flipping Physics ♫ Mr. P.: Ladies and gentle people, the bell has rung, therefore class has begun. Therefore you should be seated in your seat and ready to review electricity and magnetism dimensions, because dimensions are your? Billy, Bobby, Bo: Friends. Mr. P.: That’s […]

Electricity & Magnetism Hand Rules (part one)

Electricity and magnetism are intently related. We use moving magnets to generate electric current, as with these turbines, and electric current to make magnets. Here I’ve set up a powerful magnet with a strip of aluminum foil running perpendicular to the magnetic field lines. Remember these from the last episode? Well, I’ve set up a […]

(2 of 2) Electricity and Magnetism – Review of All Topics – AP Physics C

Mr. P: Ammeters and voltmeters. An ammeter, you need to put in series, a voltmeter, you need to put in parallel. In order to measure the current, in order to put it in, you need to have it in series, right? In order to have little change to the circuit, you need to have as […]

These Strange Metals Could Make Electronics Perfectly Efficient

Want 100% efficiency electronics? How about levitating transportation? Faster supercomputers? Duh-duh-nuh-nuh!!! Superconductors to the rescue! As long as the world you live in is close to absolute zero, that is. See, superconductors are materials with all of these amazing potential applications…but the conditions required for them to work are pretty extreme. It’s gonna take a […]

“Free Energy Magnetic Fidget Spinner” Real?

As you can see, if I move the magnet around the fidget spinner, it spins. this meme is dead Now, lets put a second magnet here. We get the same results as before. Now as you can see, these are real magnets. Now lets take a strong magnet (A neodymium magnet) near it. [Music] I […]
