Practical Investigations
The Smart Wireless Magnetic Field Sensor can be used to investigate a number of scientific
experiments such as:
Comparison of the field strength of different types of magnet, induced and permanent
Investigating materials that a magnetic field will pass through
Change of magnetic field strength with distance
Change in magnetic field strength between magnets
Directly measuring the field due to a magnet or coil
Relationship between magnetic field strength and the number of turns in a coil per unit length e.g.
use a Slinky spring toy to investigate whether the field depends on the number of turns in the coil
by stretching or compressing the coil
Investigating magnetic field patterns around magnets and coils e.g. us a Slinky spring toy to
investigate the field within the coil, how it varies along its axis and how the field in the centre
compares with that at its ends
Relationship between the magnetic field strength and the current in the coil, variation of the field of
an AC current
The variation of the magnetic field of Helmholtz coils
Variation of the field of a solenoid along its axis
