Magnetic and flux
Magnetic flux from the surroundings ( such as other wires ) may diminish or enhance the field the Hall probe intends to detect, rendering the results inaccurate.
Image: Tin_80gauss_1. 6K. jpg | The cylinder has been cooled from 4. 2 K to 1. 6 K. The current in the electromagnet has been kept constant, but the tin became superconducting at about 3 K. Magnetic flux has been expelled from the cylinder ( the Meissner effect ).
Magnetic flux is usually measured with a fluxmeter, which contains measuring coils and electronics that evaluates the change of voltage in the measuring coils to calculate the magnetic flux.
