Nearly two centuries after Faraday's failed attempts, scientists have demonstrated that Earth's continuous spin can directly ...

But if the charged objects are moving, they can also create and experience a magnetic force. One way to get moving charges is to run electric current through a wire. (This is literally a stream of ...

To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: 2 A flows through a 50 cm wire. Calculate the force acting on the wire when it is placed ...
