Bibliography [1] [2] [3] [4] [5] [6] The shape of a magnetic field around a solenoid zzz How to strengthen a magnetic field around / in a solenoid Electromagnets all consists of a current carrying conductor, however the strength of the magnetic field produced also depends on the surrounding substance. Air is not particularly good at ‘carrying’ a magnetic field and so the field around a wire is quite weak. By placing a core inside of a coil the strength of the magnetic field can be increased. By putting a ferrous (iron) core inside a solenoid, the field lines are concentrated. This has the effect of strengthening the field. Inside the core,…
