Magnetism and Electricity
... When you bring two magnets together they exert a push or pull called a magnetic force. This force results from spinning electric charges of electrons in the magnet. The force can either push magnets apart, or pull them together. Magnetic force is one of only three forces in nature that can act at a ...

... 3. Why is a solenoid used to create a stronger magnetic field? What does it resemble? To increase the magnetic force from the presence of a current, without increasing the current (because that is often dangerous), you can wrap a wire into a coil. This is called a solenoid and it is MUCH safer. By ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
