Magnetic fields do not work

Magnetic fields do no work

lmao you're so enthusiastic in this video... it makes understanding much easier and grabs your attention.

Could a magnetic field be use to attract ambient electrostatic energy electrons via an aerial antenna connected to a capacitance plate/plates next to the field ? If so - couldn't one siphon off said electrons at a rate less than the collection rate and say magnetic fields can do work perpetually ?

V×B is perpendicular to both V and B. Hence, V dot V×B is zero. 😅

Magnetic filed: in our world, the entire population is workless.
Electric field: what? 😮 So, why do you exist?
Magnetic field: just to dance and create you. We love dancing. 😅😂

Magnetic field does do work.. We learn it in electromagnetic induction

Keep hustling sir 🙏 you will get millions of subscribers

Do MagFields DO no 'work' but Are close by whenever EM spectrum "work" is happening, like a complicit, "I'm just holding her handbag while she does the work" sidekick to electrical fields? Distinctions between differing paradigm's definitions of the word e.g., 'work'. I love your teaching style thank you!!! keep on a'going!

They do, do work. Work is force x distance(displacement for specifics). The direction a force goes through is work. A magnetic force on an object does work by other magnets aligned and responding to the force and moving in the direction. On the small scale magnetic particles have a degree of alignment of the protons(quantum spin) and work can be done through that. Forget about it being a conservative field

men your explanations are good, can you do some class of electrodynamics?

[abeimnida]

wait, so does magnetic fields do work?

[yosefpatinio]

Why you defined the velocity only in the K hat direction
It can be also x hat and y hat....

[rwillikat]

Calculate the work done by torque by a uniform magnetic field on a magnetic dipole in the field region (like a current in a loop). Oh. So now you can rant about how this video was misleading, over simplified, and simply wrong. You ate too many cookies. You need to learn more physics.
