A material that does not easily allow electrical charges to move is called a...

Materials differ in how freely their electrons can move. An insulator has electrons that are tightly bound to atoms, giving it high resistance. When voltage is applied, very little current flows because the charges can’t move easily. That’s why insulators are used to prevent electric shocks and to isolate different parts of a circuit. The correct term for a material that doesn’t allow electrical charges to move readily is insulator. A conductor, by contrast, has many free electrons that move easily, so it conducts electricity well. A semiconductor conducts electricity but less readily than a metal and its conductivity can be changed with temperature, light, or doping. A magnet isn’t about electrical conduction; it relates to magnetic fields, not the ease with which charges move.
