Magnetic field sensor
Wireless magnetic field sensor for the digital laboratory: six experiments on the fields of magnets, coils and the Earth.
The wireless sensor measures the magnetic flux density and transmits the data to a digital laboratory system. It supports six experiments: the dependence of the magnetic flux density of a permanent magnet on the distance to the pole, the study of the field of a straight conductor with current, the field of a coil and solenoid depending on the current and the number of turns, the measurement of a uniform field inside Helmholtz coils, the study of the horizontal component of the Earth’s magnetic field and mapping the interaction of permanent magnets. The sensor is used in laboratory activities and demonstrations on electromagnetism in a physics course.
- Dependence of a permanent magnet’s magnetic flux density on distance from its pole
- Study of the magnetic field of a straight conductor with current (Biot-Savart-Laplace law)
- Coil and solenoid fields: dependence of magnetic flux density on current and number of turns
- Measuring a uniform field inside Helmholtz coils
- Study of the horizontal component of the Earth's magnetic field
- Mapping the interaction of permanent magnets
