Subject: Will touching a magnet on waveguide cover in microwave cause microwaves?

Our microwave contained a piece inside of the oven that appeared to be melted. 
Since the manual said that the oven should not be used if any of the metal 
parts on the interior were damaged, I held a magnet up to what I thought was 
the waveguide cover to determine whether it was metal. It was not metal and 
therefore we assumed everything is fine. However, I started wondering as to 
whether holding a magnet up to the waveguide cover (waveguide and magnetron is 
located on the other side) could cause microwaves to be produced - thereby 
exposing me to microwaves. Or is it possible that holding a magnet up to the 
waveguide cover could damage the magnetron? I appreciate your time and 
consideration in answering my question.
