they only use electricity when an appliance is plugged in and switched on
If your laptop is turned on and it looks like it's plugged in, the batter could possibly be dead or the connection from the outlet to the computer has a problem.

it is not recommended to use your cell phone when charging, this could cause the circuits to short. Ideally you should charge your battery when your phone is turned off
The formula you are looking for is I = W/E. W = kW x 1000.
Most Electric Ranges are plugged into a 50 A breaker for good reason. When everything is turned on it will likely draw more than 30 A. The first step is to find the rating plate on your range and see the current rating. If great than 24 A you shouldn't use 30 A breaker. Make sure connection wire is sized for the correct amperage.
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
