Superconductors can be used to make electromagnets that are 10 times stronger than the strongest conventional electromagnets. These superconducting magnets are used in the construction of magnetic resonance imaging (MRI) devices that can be used to make high-resolution images of the human body. Superconducting magnets have many other uses.

Resistance is a measure of how difficult it is for current pass through a material. Both properties play an important role in the use and analysis of electric circuits. We will also see in subsequent chapters that current plays a key role in the generation of magnetic fields and electromagnetic waves.
