Metal in Microwave?

My cousin left a metal spoon submerjed in a bowl of food being microwaved and only realized it after she microwaved the food. Now the microwave isn't heating anything. It still runs the same as before, but it isn't heating, did she destoy the microwave? or can we salvage it? Is it a fuse? Would it be very expensive to fix? Thanks anyone.
