  We study the angular dependence of ferromagnetic resonance (FMR) in
Ni$_{36}$Fe$_{64}$ wires using both traditional microwave-absorption and
electrical-detection techniques. In our experiments we apply a static magnetic
field at an angle $\theta$ with respect to the wire, while the microwave
current, which is responsible for driving FMR, is always flowing along the
wire. For different $\theta$s we find a very similar behavior for both
microwave-absorption and electrically-detected FMR -- the resonance magnetic
field follows a simple "$1/\cos(\theta)$" dependence. This simple behavior
highlights the importance of the relative orientation between the driving
current and magnetic field. We also investigated the dependence of the
electrically detected FMR on dc and rf (microwave) current magnitudes. As
expected, the resonance signal increases linearly with both the applied dc
current and the microwave power.
