When goofing around with a magnet, one will find that some small stuff (with some Fe in it) will become magnetized (to whatever degree).

What would be required to magnetize something of pretty substantial size - like a fire hydrant or a manhole cover or the side of a car ?

All kinds of stuff could be magnetized - just for laughs - if it's practical to do so. (I don't need admonitions about the potential damage/problems that magnets can cause).

And would it stay magnetized ?

Does anyone know where I can download the solutions manual / answer key for "Fundamentals of Physics" by holliday, walker & resnick 7th Ed, really helpful when reviewing for exams.

I am looking for the PDF version and not the actual book.

Thanks

I called my electric company and they have no idea about this product.

The Power-Save 1200™ was designed with the homeowner in mind, providing lower energy bills, increased motor and appliance life, as well as surge and lightning protection for all of the equipment inside of your house.

Residential customers throughout the United States and Canada see a realized savings of 8% - 10% minimum and as much as 25% on their electrical usage (and thus power bills). All Power-Save products are backed by a warranty for surge and lighting
