1140 - Wireless Magnetic Field Sensor

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
