Can an iphone generate any kind of magnetic field?

I was wondering if there was any script or anyway to use the iphone to generate either a magnetic field or some kind of pulse induction.

im sure you can't without having some sort of actual coil but i just thought i would ask...i figured there might be a way to create an electronic pulse possible but i don't think there is anyway of getting around the need for magnetic material.

i have heard of ways to create a small pulse using an iphone and an lcd display on a laptop for instance but i think all that does is destroy hard drives, something that would be ridiculous to even attempt. i know that hard drives have some sort of magnet but i don't think the iphone does...

Er... assuming the iPhone still runs on electricity (voltage and current) then yes, it can generate "a" magnetic field. Whether or not it's strong enough to do anything useful is a separate matter.
OK, sure, as part of it's normal operation it may generate an amazingly weak field. But it's not something you can turn on and off. And there is no specialist hardware in the device specifically there to do this that could be software controlled.

Radio waves are electromagnetic fields. An iPhone has at least 3 intended radio transmitters, celllar, wifi and bluetooth. Other circuits transmit unintended high frequency radio noise, but these have to be really tiny for the device to get FCC certification. The power circuit, audio amp and 2 speakers may create some lower audio frequency electromagnetic fields as well.

[doublepost=1522156712][/doublepost]An I phone does create a magnetic field whether on or off. Try this experiment. Put a directional compass on a flat level surface. Let the compass come to a rest pointing North. Now hold you iPhone next to the compass and turn it on. Move the iPhone around the compass and the directional needle will move. Now see what happens when the phone is turned off.
