Where Can I Find Helpful Information on Electromagnetic Braking?

AI Thread Summary
The discussion centers around finding resources for a school project on electromagnetic braking, specifically in relation to its application in amusement rides like the "spac probe" at Australia Wonderland and in trains. Participants suggest using Google to search for specific types of electromagnetic brakes, with an emphasis on automotive applications. Several helpful links are provided, including manufacturer websites and technical briefs, which could assist in gathering information. Additionally, contacting manufacturers directly and utilizing local library resources are recommended as alternative methods for obtaining information.

Hi, I'm doing a school project regarding electromagnetic braking I just wondered if anyone could point me in the direction of some good websites which could help me?
 
Physics news on Phys.org
use in the "spac probe" a park ride in "Australlia Wonderland" in sydney it is a free fall ride that uses electomagnetic brake to stop


some train alos uses electomagnetic brake


links ? not sure

try search google
 
What kind of electr-mag brakes are you looking for? I'm assuming automotive, but here's a few links which may point you in the right direction.

http://www.brakeclutch.com/ manufacturer

http://www.powertransmission.com/cgi-bin/newleads.cgi?Electromagnetic%20Brakes a list of manufacturers of electr-mag brakes

Don't know how much this will help, if all else fails, contact the manufacturers I listed and maybe they could help. When all else fails, check the local library.

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
