New Tahoe with wireless charging and an Otterbox on my Galaxy won't charge

I just picked up a new Tahoe with wireless charging pad but my Galaxy won't charge while in the Otterbox. Is there some type of "magnet" or something that can go between the phone and case to allow the wireless charging pad to work? or do I have to buy another type of case?
