Do I need to shield my turned-off cell phone at night because it emits magnetic fields? I keep it bedside for emergenies.

If the phone is completely off, you shouldn't pick up any fields from it. If the phone is in airplane mode with WiFi/Bluetooth off, then magnetic fields can still be emitted. Keep the phone at least 3-5 feet away if you want to use it for an alarm clock in Airplane mode and with WiFi/Bluetooth off. At least then no radiofrequency (wireless) microwave radiation signals will be emitted. I use my phone as an alarm clock at times, but I keep the phone at least 3-5 feet away and always make sure Airplane mode is on and WiFi/Bluetooth are off. Some phones like to turn WiFi/Bluetooth on by themselves for some reason.
