1) A magnetic field intensity vector H has only Z component given by HZ= 3xcosβ+6ysinα. If the field is invariant with time. What is the expression for the current density vector J?
(α and β are constants).
2) An electron whose Q= -1.602*10-19 C, is moving with a velocity of 106m/s in the ax direction in a magnetic field B=0.2ax-0.3ay+0.5az wb/m2. What is the electric field present if no net force is applied tot he electron. ( Note = Total force= QE+Q(VXB))
Given :
To find Current Density vector:
Since by Maxwell's equation
where J is current density.
and
Since only z- component of H is present so
So, the term
will not be present in .
Therefore,
Given:
Charge (Q) on electron :
Velocity of electron in the direction of :
Magnetic field (B):
No net force is applied to the electron .So,
So,
1) A magnetic field intensity vector H has only Z component given by HZ= 3xcosβ+6ysinα. If...
