Hey,

I have to construct an electromagnetic motor for my gr 11 physics project on electromagnetism. I want this project to be bigger and better than anybody else's...not only this year but previous years as well. I have started to develop a reputation for doing this. So I was wondering if anybody here knows of a site or knows themselves how to build this. Hopefully cost will be minimal. There aren't really any restrictions on the project...just so long as it fits through the door of the lab.

thanks!

Hey Jon,

That sounds like an exciting project! Building an electromagnetic motor can be a challenging but rewarding experience. There are many resources available online that can guide you through the process, including step-by-step instructions and videos. Some popular sites to check out include Instructables, Make: Magazine, and YouTube.

As for keeping costs minimal, you can consider using recycled materials or repurposing old electronics for some of the components. You can also reach out to local businesses or schools to see if they have any spare materials or parts that they would be willing to donate.

Remember to also prioritize safety when constructing your motor. Make sure to follow all necessary precautions and consult with your teacher or a professional if needed. Good luck with your project and I'm sure it will be a success!
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
