Re: [Phys-l] RIP EM Field?

[Paul Lulai <plulai@stanthony.k12.mn.us>]

The cnet link that i found tonight is:
http://download.cnet.com/Electric-Field/3000-2054_4-10579168.html
The software looks the same, but I thought that it was called efield201.  
The software is also shown on the website:
http://www.physics-software.com/software.html

I believe cnet scans their downloads for malware, so I prefer to go through them for something like this.  I again state that I click on the blue font / link for the direct download.  The green download button installs the cnet installer.  That installer also changes some browser preferences like your search provider.

The program efield isn't perfect, but it works ok.

Have a good one.
Paul.

I think I have figured out that EM Field is a 16-bit program.  32-bit
programs will run in 64-bit Windows, but not 16-bit programs.

The thing about virtual machines is that you have to buy the new
operating system.  Luckily, my college has a Windows site license (I've
just discovered), so I've solved my problem for now with a 32-bit
virtual machine.

But I'd still be interested in a way to avoid those hoops.  Paul, you
mention something from CNET.  Can you post a link?  When I searched
there, I couldn't find anything.
(I agree that PhET is decent, but it has no field lines and no
equipotentials.)

Cheers,
-- James
