Suppose a gravitational wave propagating through space encounters a strong magnetic field (for example the wave might pass through a magnetar with a B field strength of [itex]10^{11}[/itex] Tesla). Would there be any observable perturbation in the magnetic field itself? In other words would the gravitational wave create an oscillation in the magnetic field which could potentially be observed?(adsbygoogle = window.adsbygoogle || []).push({});

I found one paper here:

http://www.sciencedirect.com/science/article/pii/S0370269303004155

which indicates that the answer is yes. But I haven't been able to find much more on this in terms of calculations or even just a simple explanation of what would happen.

The obvious implication is that if GWs perturb EM fields, this could be another avenue to observe them, provided we put a magnetic sensor in the right place, etc.
