Can I erase a hard drive without being able to connect it to a computer?

I don't think a fridge magnet has enough pull to corrupt data on a HDD. If it were powerful enough you would need to move it in circles. I am thinking more like some kind of electro-magnet, but still you would be hard pressed to get one that you know will get the job done. Unless you work at a junk-yard.

Good luck on cleaning up your old data with out a connection.
