Search Results<span>By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. ... You can make a temporary magnet by stroking apiece of iron or steel (such as a needle) along with a permanent magnet.

The ions are in fixed positions.
Explanation:
Ionic solids are poor conductors of electricity because their ions are fixed in position. Their ions are not free to move about. They are fixed in crystal lattices.
- For the conduction of electricity, compounds must possess free mobile electrons and moving ions in solution.
- Ionic compounds are formed by the electrostatic attraction between a metallic and non-metallic ion.
- They actually contain ions but their ions are locked up.
- They are not free to move about.
- Electrical conduction involves ion mobility.
- In molten and aqueous forms, they are able to conduct electricity because their ions are then mobile.

Answer:
A solenoid is a device comprised of a coil of wire, the housing and a moveable plunger (armature). When an electrical current is introduced, a magnetic field forms around the coil which draws the plunger in. More simply, a solenoid converts electrical energy into mechanical work.
Explanation:
The coil is made of many turns of tightly wound copper wire. When an electrical current flows through this wire, a strong magnetic field/flux is created.
The housing, usually made of iron or steel, surrounds the coil concentrating the magnetic field generated by the coil.
The plunger is attracted to the stop through the concentration of the magnetic field providing the mechanical force to do work.
