Earth’s magnetic north pole has been shifting gradually for centuries due to the movement of molten metals in the planet’s outer core. In the 1990s, magnetic north began to experience an ...

Your thumb points to the north pole of the electromagnet. The magnetic field produced by the current in a coil of wire: is very similar to the field of a bar magnet; reverses when the direction of ...
