My dentist says you can't have a gold crown atop a tooth which has a silver filling since it creates a magnetic pull?

Magnet, no: Galvanic action, possibly. There would be two dissimilar metals contacting each other, and with the salts in your saliva, you can have an exchange of ions, like a battery. Have your dentist explain this to you further and your treatment options.

Galvanic shock: Gives a sharp and jolting feeling due to electric current caused by these metals.

Yes, the possibility exists for this phenomenon in some patients. However, it's fairly rare. Consider a ceramic crown to eliminate the possibiliy

Trust your DDS: Gold crowns, on top of amalgam, create a permanent galvanic cell and compromise the outcome.

My opinion\advice: Technically and theoretically, two dissimilar metals in the presence of saliva which is acidic may create a galvanic response causing some 'shock'. In reality, this has never been a problem for me or my patients. It can happen and is often mild and temporary. Other options are to replace the silver filling with a composite filling, or use a ceramic crown.
