Question

1) Given a current of 1.1[A]; a coil radius of 0.14[m]; and N=130, then what is the strength of the magnetic field in milliTeslas?                                   [mT]

2). Let's say that you are given a magnetic field
B = 0.000919[Teslas]. You also have an
average V / d2 = 18897[V/m2];
what is the value for e / m ?
[units are suppressed
(Report your answer with three sig. figs. and use scientific notation "E". ie. 1.98E11

3) What is the accepted value for e/m?
Use Scientific Notation (i.e. 1.76E11)
e m-1 = ---------------------[C kg-1]

Explanation / Answer

1.

Magnetic field due to circular coil with N turns is

B=uoNI/2pir =(4pi*10-7)*130*1.1/2pi*0.14

B=0.204 mT
