The strength of an electromagnetic can be increased by _______ the current through the wire and by __________ the number of wire turns around the core. A stronger magnetic will also be produced if ______ wire is wrapped around a core consisting of a ________. In general, ________ the size of the electromagnetic increases the strength.
The strength of an electromagnetic can be increased by increasing the current through the wire and by increasing the number of wire turns around the core. A stronger magnetic will also be produced if thick wire is wrapped around a core consisting of a metal. In general, increasing the size of the electromagnetic increases the strength.
