Coils. A wire coil can be used to concentrate magnetic flux in a controlled area. The most common form of coil, known as a solenoid, can be a single loop of wire or multiple turns in series.The diagram on the left represents the magnetic field in a typical solenoid.By winding multiple turns in the same direction its possible to increase the total magnetic field strength.elmholtz Coils. This type of coil is used to generate a uniform magnetic field. Two coils are held parallel to each other at a distance less than their diameter. The field between the coils should be quite uniform, providing the strength of the overall field is high enough.
