Explore the nature and strengths of magnetic fields of solenoids and permanent magnets with this robust sensor which houses two switchable Hall effect transducers to measure accurately both Radial and Axial magnetic fields.

Applications

Physics:

• Magnetic field in a coil
• Magnetic field in a Slinky Spring
• Magnetic field of magnets 
• Magnetic field of a solenoid

General:

• Mapping a magnetic field
• Exploring electromagnets

There are two Hall Effect devices in this sensor, placed at right angles to each other. This enables fields along the axis of the Magnetic Field Sensor (the axial field) or at right angles (the radial field) to be measured.
