[Announcement] Electricity and Magnetism Practice Launch

We're happy to announce that we've launched a new practice section on Brilliant today: Electricity & Magnetism Practice.

So, if you're interested in circuits, charges, voltage, resistance, and all things electro-magnetic, head over and check it out.

You'll also notice that many of the wiki pages for this new section have not yet been written. Feel free to pitch in and contribute a write up for the community if you're already familiar with E&M.

Are the following 2 statements true or false?

(a) Two particles with the same charge will repel or drive away from each other.
(b) Two particles with opposite charges will be attracted to each other.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I'm really excited for the new practice section for E & M. Brilliant is always brilliant in what they do :).

(@Arron Kau Just to let you know, Electricity is spelled wrong on the link. Just pointing that out.. slowly backs off )

I love this topic but when does "Corcuits" and " Magnetic Fields " courses comes? Please let me now

Onur Yiğit Taş - 11 months ago

I am an Electrical Engineer and I am interested.

Shashank Singh - 6 years, 6 months ago

yes above statements are true

Shashank Singh - 6 years, 6 months ago

a)Is true b)Is true It follows the law of ''Static electricity''.It Is also similar to law of magnetism which state that ''Like pole of magnets repel nd unlike pole of magnet attract.''

Ayanlaja Adebola - 6 years, 6 months ago

that's really a gr8 news!! <##>

Palash Som - 6 years, 6 months ago
