# Rectangular coil current problem

please, i want to be sure of my password and user name can it be posted to email? also, idon't know how to submit questions can the guide lines be posted as well? Thank you.

A rectangular coil, carrying a current of 400pie amperes, lies in the z=0 plane with its corners at the points (a,b,0), (-a,b,0), (-a,-b,0) and (a,-b,0).

(a) find an expression for the magnetic field strength H at a point (x,y,0) within the coil and evaluate it at points (0,0,0) and (2,1.5,0) given a=4' b=3 netres.

You can get it posted to an email as long as you gave an address when you signed up, the easiest way I can think of doing this is to log out then incorrectly log in, ie mess up your password, then a link will appear that allows you to have username and password sent to you.

The second part belongs in homework help section, if you want to edit it out and move it over to there.
