Why am I talking about electric fields? Don't I want to talk about current (and power) instead? Yes. So, there is a reason to consider these curly fields. If the coil of wire in the motor is ...

There is an electric current in a wire because there is an electric field inside the wire. It's this electric field that pushes the free electrons to get them to move along. If you imagine that ...

However, the field quickly becomes much weaker as you move away. If you run an electric current through a wire, it will produce a magnetic field around the wire. The direction of this magnetic ...

With their electric fields, the bees can move each other’s ... “Unless a bee-keeper puts their hive directly under a high-voltage electric wire outside, the effects should be limited.” ...

Electric and magnetic fields are both components of an electromagnetic ... the electrons in a wire that move as a current to create a magnetic force travel at about a millimetre per second ...
