Electromagnet questions.

High guys, I'm building an electromagnet for a project and wanted to know a few questions.

1)I've read online on how to make electromagnets, but the videos that came with the instructions make it seem that the method of making an electromagnet that was shown, is weak. (They could only pick up paperclips.) How can I make a STRONG electromagnet? (Would I need to have Lots of Voltage? Good metal? Good wire?)

2)Can electromagnets have any side effects on your health? (I ask this because, the project I thought of has those electromagnets on your feet and other limbs. I need to know if electromagnets are safe, and cant harm people.)

Thanks guys.

Magnets are safe, even very strong ones. They are what mri machines use. As for strentgh, sorry, it is hard to make a strong one, you would need a huge power supply. What are you making, a james bond esqe magnet watch?

Cant say. Sort of..kinda.. a small invention. xDD

Hmm, Well. Where could I find some strong magnents? Like ones that would be strong enough to hold your feet to something, but easy enough pull apart from that something, just incase of an emergency?

"Rare Earth Magnets/Niodimiyum magnets" are powerful right?

they are very strong, but if you want them to be big enough, you will have to pay a lot of cash. the little ones are cheap, big ones aint. what ARE you making? i love magnet projects, so i would like to know.

Reminds me of the James bond Mythbusters special.
